CHECK IF SOMEONE IS ACCESSING MY INTERNET CONNECTION

All of the laptops manufactured these days have built-in wireless adapter/wi-fi. Most of the people these days have their own wireless adapter or router connected to their desktops. Don't you know that they can connect to someone else's network wirelessly?

If you do have wireless router, gateway or other wireless networking devices (ex. WRT54G-LINKSYS wireless router or WCG200 for gateway), don't you know that you can connect 21 wireless PCs to it? And if your router is not secured, don't you know that someone in your area having built-in Wi-Fi on their PCs can connect to your own network without even noticing it. Maybe you'll find one day that you are having slow internet connection because of too many users doing multiple applications in your network. Or if you subscribe for fast internet connection to your ISP, maybe you'll might not even notice that you're not the only one connected to your internet.

Do you have Linksys router? You can check it on your router's setup page!

Here's the steps to check if there are other computers that you don't own are connected to your Linksys router without your permission.

1. Check your PC's/PCs MAC address. Write it down on a piece of paper. How to do that? Check my article: "HOW TO CHECK MY COMPUTER'S MAC ADDRESS".

NOTE: In Windows 2000 or XP, MAC address is the same with "Physical Address". In Windows 98 or lower version, it is called "Network Address".

2. Access router's set-up page. If you do have Linksys router and don't know how to do that, go to my article: "HOW TO ACCESS LINKSYS ROUTER'S SET-UP PAGE".

3. Go to "Wireless" tab.

4. Under "Wireless" tab, go to "Wireless Network access" or "Wireless MAC Filter".

5. Click "Edit MAC Filter List"

6. You will see "Wireless MAC Client" window. On this window, you will see "ACTIVE PC" option. Listed here is the MAC Address connected to your router. Now, match the MAC address of your PC from the MAC addresses listed there. Did you see MAC address that does not belong to your PC/PCs? That may be someone else's PC. Then, try to enable MAC filter. Do you know how to enable MAC filter? Go to my article: "HOW TO SETUP WIRELESS MAC FILTER ON A LINKSYS ROUTER?".

Easy WayTO TROUBLESHOOT LINKSYS ROUTERS FOR DSL ISP?

Many people experienced problem in their router after their router was turned off. Upon turning on the router, the computer, and open your browser, what you've got is "Page Cannot Be Displayed" message.

What you do is you try to type again the web address (URL) . But upon trying that for several times, you tried to visit another site, and what you get is the same screen, "Page Cannot be Displayed". Oh no, you don't have internet connection! What most people do after seeing this message is they contact their ISP (Internet Service Provider). That a great idea! But contacting ISP is not that too easy! You are on queue of thousands of people trying to reach the ISP's technical support dept.! You wait for 30 minutes, 1 hour or 2 hours. You are now losing your patient for waiting on the line and hearing those irritating background music. After waiting, you finally got the tech support agent. You burst out your feeling and you can't help yourself from getting angry. But what happened is, the tech supp agent hanged up. Oh, gosh! This is what you get after experiencing the problem and waiting on the phone! You are now very aggravated! You almost throw your phone and kick off your computer! I think you better try this step by step procedures first before calling your ISP. This is proven to work for DSL ISP. Try this steps and you'll find how easy it is troubleshoot your own Linksys routerwithout calling your ISP. 1. Check the cable connection. Make sure that the modem is connected to the "internet port" on the back of the router. And make sure that the PC is connected to one of the ethernet ports on the back of the linksys router. 2. If cable connections are good, turn off the PC and if it is already off, turn off the router and then the modem. Wait for 2-5 mins. Then turn on the modem and if all the lights on the modem are steady, turn on the Linksys router, after the Linksys router 3. Check if you have valid IP address. it should be 192.168.1.x. 4. If still you don't have internet, log on the router's setup page. (don't know how? go to my article "HOW TO ACCESS LINKSYS ROUTER"S SETUP PAGE) 5. Go to the SETUP page. Configure PPPoe. The format is usually "username@isp.net" . The other is just username. For example : azumi@starhub.net. And then type your password given by your ISP. 6. Select "keep Alive" option. 7. Check STATUS tab. If status says "CONNECTED", you have internet now. If the status says "DISCONNECTED", click "CONNECT". Do that twice. If Internet IP address is 192.168.1.x, Change the router's LAN IP address in the SETUP page to 192.168.x.1. Then follow step 2.

What MTS Sucks

The MTS and MBLAZE  Short Review.
The new provider MTS Sucks bigtime. the Mblaze sucks too.

Do not think about going for it if u want to use it in rural places.
They boast about the urban cities linke Delhi, Pune, Mumbai that the coverage is very good.

Their promotional ads show that the service is faster than lightning speed but its not even up to the mark.

Some users have complained bout the speed to be as low as 1kbps. On healthy torrents the speed is 0.1 kbps-6kbps.

The customer service is the worst ever. There is no one to answer your call for days.

I will update the Serial Numbers and Mobile numbers of MTS and MBlaze soon.

MTS Sucks. MBlaze Sucks. MTS Data Card.

Main Cisco Connect problems solution

I am posting all the possible FAQs regarding Cisco Connect.The New series of routers from Linksys or Cisco are just amazing, in regards of both, connectivity and range.1.       What is Cisco Connect?

Cisco Connect is a software program that allows you to access Valet settings and its unique features. Using Cisco Connect, you can view and change the Valet or Linksys E-Series name and password and set up parental controls where you can restrict Internet access to computer users in your home. You can also update and create an Easy Setup Key and turn on Safe Web Surfing.
NOTE:  Cisco Valet is currently available only in North America. The Linksys E2100L router is only available in the US.
To learn how to open Cisco Connect on your computer, click here.

2.       What computer operating systems does Cisco Connect support?

Cisco Connect supports these operating systems:
- Microsoft Windows XP SP3
- Microsoft Windows Vista SP1 and above
- Microsoft Windows 7
- Mac OS X Tiger 10.4.9
- Mac OS X Tiger 10.4.11
- Mac OS X Leopard 10.5.8
- Mac OS X Snow Leopard 10.6.1

3.       What wireless adapter requirements need to be met when using Cisco Connect?

To work with Cisco Connect, wireless adapters must support WPA and WPA2 encryption.

4.       Why can’t I use Cisco Connect when I’m away from home?

Cisco Connect can only be opened when you are connected to your Valet or Linksys E-Series. When you are at a coffee shop or at school, you are connected to a different network, so Cisco Connect will not work. 
NOTE: Cisco Valet is currently available only in North America. The Linksys E2100L router is only available in the US.

5.       What’s the difference between Safe web surfing and parental controls?

When Safe web surfing is turned ON as you’re surfing the Internet and are about to open a potentially harmful site, an alert displays in your browser telling you that the site may be harmful to your computer or to your personal data. There are certain sites on the Internet that are “flagged” as potentially harmful, meaning they may contain viruses, install malware on your computer, or attempt to access your personal data. You can continue on to the site, or decide not to open it. When Safe web surfing is turned on, it applies to all computers connected to the Valet or Valet Plus.
Parental controls allows you to restrict the Internet on specific computers in your home. You can restrict access to the Internet for specific days and times, or allow Internet access but restrict access to specific Web content.
NOTE:  Cisco Valet is currently available only in North America. The Linksys E2100L router is only available in the US.
Parental controls in Cisco Connect can be set up for up to 10 computers or devices.

6.       Why do I see duplicate names for computers and devices when setting up parental controls?

When setting up parental controls, you decide which computers and devices the Internet restrictions apply to. In the Set up parental controls for dialog box sometimes a computer or device name might be listed more than once. This can happen if:

• A computer has connected to the Valet or Linksys E-Series both wirelessly and with a wired connection.

• You have two of the same kinds of devices, such as phones, and both are listed with the same manufacturer name.

• You’ve given the same name to more than one computer or device. If you want to set parental controls for an item that is listed
more than once, select all instances of the name in the Set up parental controls for dialog box. This ensures that the Internet
restrictions you set will apply to that computer or device. 

NOTE:  Cisco Valet is currently available only in North America. The Linksys E2100L router is only available in the US.Parental controls in Cisco Connect can be set up for up to 10 computers or devices. 7.       I forgot my parental controls password and the answer to my secret question. What should I do?
In a scenario like this, we suggest that you perform the following steps:Step 1:
Reset your Valet or Linksys E-Series by holding down the reset button for 10-15 seconds.

Step 2:
Uninstall Cisco Connect.

Step 3:
Insert your updated Easy Setup Key to restore your Valet or Linksys E-Series settings. You will need to reconfigure Parental controls. If you do not have an updated Easy Setup Key, you will need to run your Valet or Linksys E-Series installation again.

NOTE: Cisco Valet is currently available only in North America. The Linksys E2100L router is only available in the US.8.       What happens if I uninstall Cisco Connect?

When you uninstall Cisco Connect, all Valet or Linksys E-Series settings remain unchanged. These settings include the Valet or Linksys E-Series, password, guest access, and parental controls. For example, if you have parental controls set to block Internet access for school nights, those settings remain in effect after you uninstall Cisco Connect. To remove or change Valet or Linksys E-Series settings after you uninstall Cisco Connect, you need to reset the Valet or Linksys E-Series to its original settings, and then use the Valet or Linksys E-Series Web-based utility. Refer to the Valet or Linksys E-Series User Guide for details about using the Web-based utility.

NOTE: Cisco Valet is currently available only in North America. The Linksys E2100L router is only available in the US.

9.       What is a Valet or Linksys E-Series name and password?

Your Valet or Linksys E-Series provides a private network for the computers and devices (phones, gaming systems, PDAs) in your home. Using the Valet or Linksys E-Series, those computers and devices can share one Internet connection and communicate with each other to share files, photos, printers, etc. The Valet or Linksys E-Series name and password are required for any computer or device you connect to your Valet or Linksys E-Series. This prevents neighbors (or strangers) from accessing your network, and potentially your personal information. You can use the pre-defined name and password that comes with your Valet or Linksys E-Series, or you can change them to something you prefer. To change the name or password, open Cisco Connect and choose Valet settings for Valets or Router settings for Routers. Be sure to update the Easy Setup Key when you do this.

Important: You will need to manually reconnect your computers or devices using the new name and password to your wireless network should you change the Valet or Linksys E-Series name or password. You may also use and insert the updated Easy Setup Key into that computer to automatically reconnect to your wireless network. To know how to update your Easy Setup Key, click here.

NOTE: Cisco Valet is currently available only in North America. The Linksys E2100L router is only available in the US.

10.      I changed my Valet or Linksys E-Series name and password. How can I connect my other computers?

If you used Cisco Connect to change the Valet or Linksys E-Series name or password, you will be prompted to update the Easy Setup Key during that process.
If you updated the key, take that key to the other computers you want to connect to the Valet or Linksys E-Series and insert it into any available USB port. The Cisco Connect software will then update the computer’s settings with the new name and password you have made. This will reconnect the computer to the wireless network.
If the Easy Setup Key was not updated when you changed the name or password, open Cisco Connect, click Valet settings for Valets or Router settings for Routers, and then click Update or create Key to update your Key. Then, insert the updated Key into the computer you’re trying to connect. This will update the name and password settings and connect the computer to the Valet or Linksys E-Series.
NOTE: When changing your Valet or Linksys E-Series Name and Password, we recommend that you always do so using the Change option in Cisco Connect. Changing the Name and Password via the Advanced settings option or Web-based utility will prevent you from using Cisco Connect.

To learn how to change your Valet or Linksys E-Series Name or Password, please click here.

To learn how to find out the Wireless name or the Password, of your Valet or E-Series router please click here.

11.      I want to update my Valet or Linksys E-Series settings on my computer, but I don’t have a free USB port to insert the Easy Setup Key into. What can I do?

If you’re using a USB wireless adapter, you can remove the wireless adapter temporarily and insert your Easy Setup Key to update the settings on your computer. When the Valet or Linksys E-Series settings are updated, remove the Key and re-insert your wireless adapter.

NOTE: Cisco Valet is currently available only in North America. The Linksys E2100L router is only available in the US.

12.     What are the Advanced Settings?

This is a Web-based utility used for setting advanced Valet or Linksys E-Series features, such as wireless encryption, SSID, and others. You should not use this utility unless you have configured routers in the past. It’s best to use Cisco Connect’s Valet settings or Router settings to make any changes. To access the utility, use the Valet password.
Important: If you change the Valet or Linksys E-Series password using the Valet settings or Router settings option in Cisco Connect, the change is also applied to the Web-based utility. To access the utility, you have to use the new password.

NOTE: Cisco Valet is currently available only in North America. The Linksys E2100L router is only available in the US.

13.     My Advanced Settings have been changed and now I can’t use Cisco Connect. What can I do?

If you or someone else used the Advanced Settings to make changes to the Valet or Linksys E-Series settings, those settings were applied directly to the Valet or Linksys E-Series and you can no longer use Cisco Connect. You can either continue to use the Valet or Linksys E-Series Advanced Settings to view and change Valet or Linksys E-Series settings, or you can reset your Valet or Linksys E-Series. If you reset your Valet or Linksys E-Series, the name, password, and other settings return to the default settings – the way they were when you first installed the Valet or Linksys E-Series. You can then use Cisco Connect to manage settings.

What is Access Point? How to configure it?

Access Point can be defined as a device that is used as a wireless hotspot. A Router or a Modem can be called as an Access Point. In simple words, a device that helps you to connect to a wireless network is called as an Access point.






Access Point can be configured in 2 ways.
    1.   If the Access Point is a Router or a Modem, You need to configure it along with the internet settings of the router/modem. Generally the Internet Service Provider (ISP)'s settings are not necessary to configure an Access Point. The settings you need are the SSID (Name of the Wireless Network), Wireless Channel and the Wireless Security. Click here to know more about wireless settings and here to know about Wireless Security.




    2.   If the Router or the Modem you using doen not have wireless functionality in it, than you can connect the Access Point with a cable to the router/modem, configure the wireless settings and start broadcasting.




To use the Access Point as a Repeater, view this post.


Lets see about the Cisco WAP200E Access Point. 


WAP200E is a popular for its stability and good consistent performance. If you happen to face any issues with WAP200E, you don't need to reconfigure all the settings. Rather just turn off the device, wait for 5 seconds and turn it back on. It will Work absolutely fine. Weather-resistant housing allows for outdoor deployments, and Power over Ethernet (PoE) functionality frees the device from proximity to an electrical outlet. You don't need to connect this device to any power outlet. Its RangeBooster technology reaches up to twice as far as standard 802.11g, with reduced dead spots and improved throughput up to 35 percent.

Get back your Dead or not responding Router

Seize The Moment With TFTP




You can use the TFTP (Trivial File Transfer Protocol (define)) command-line utility to upload fresh firmware to the router in its brief moment of wakefulness. Windows, OS X and Linux all include TFTP clients.



First, you need a .bin file containing the known good firmware. You can visit the Linksys site as described above and download the .zip version of the firmware, which includes the .bin file. You can even use a .bin file for an open source firmware, so long as you choose one that's stable and tested and is the correct version for your router (or else you start this whole process all over again).



Windows users need some dexterity here. First, remove power from your router. Open two command prompt windows. In one, you will set up your TFTP command.



Type (but do not yet press enter):



tftp –i 192.168.1.1 PUT firmwarefile.bin



In the second command prompt, enter:



ping –t 192.168.1.1



Run the ping command, which will begin probing and failing to reach the router. Now change window focus to your TFTP command.



Apply power to the router. Watch the ping window for a response, then hit enter in the TFTP window!



Miss by a beat and you’re too late – the pings will fail and your moment has passed. Cut power to the router and repeat the process. You need to start the TFTP the moment you see a successful ping.



For OS X and Linux users, the principle is the same, but the process is easier. First, remove power from your router. Open a terminal window and enter the commands:



tftp 192.168.1.1

binary

rexmt 1

timeout 60

trace

tftp> put firmwarefile.bin



Now apply power to your router. The tftp client will continuously retry uploading the firmware until the router responds. Hopefully, the router will briefly awaken, allowing the firmware upgrade to be sent. About two minutes later, the router will reset and become operational with the new firmware.



If your router simply refuses ever to respond to a ping at 192.168.1.1 despite all these tricks, things are looking grim. You might want to start saving up $60 worth of router replacement kitty.



Short Circuits



You’re desperate. Nothing has worked, and your router is probably a doorstop. At this point, you might want to consider cracking the lid. This will certainly void your warranty, but then again, whatever bricked it this badly probably already did that.



There remains a small glimmer of hope. That glimmer is actually a spark, which, if you’re feeling brave, is what you may need to create.



Two invasive methods of short-circuiting your router have been reported successful. These techniques are controversial. Some in the router modifying community are opposed to even discussing these techniques. We’re not here to judge, nor do we endorse them. If you err even slightly, you’ll probably permanently destroy the router and possibly create a small fire hazard. Take precautions. Rubber-soled shoes and a fire extinguisher, minimum.



Unplug your router. Disassemble the case. On many models of WRT, the case is not held together with screws. You can press down on the top front to pop off the face. Manually untwist the two antennas. Press down on the bottom rear to pop off the backplane. You should be left with a tiny “I paid $60 for this?” circuit board attached to a plastic bottom panel. (Note that some router models do include a couple of screws which are accessible under the rubber feet.)



Look for the flash chip, which is typically marked “Intel” and is toward the front of the circuit board where the LEDs are. The pins on this chip are numbered at the corners – 1, 24, 25, and 48. Small white triangles mark every 5 pins.



The two most successful “shortcuts” have been on routers of V4 or less, using one of two methods: short pins 15 and 16, or short pin 16 to earth via the left antenna input. [At least one reader wrote to tell us that on the WRT54GL v1.1, he had to use pins 16 and 17. Your mileage my vary, kids.]



A small jeweler’s screwdrivers or the tip of a multimeter can be used to short pins 15 and 16. First, apply power to the router and depress the reset button for 30 seconds. Cycle the power again. Short pins 15 and 16, and depress the reset button for another 30 seconds. Now try to ping the router. Many report success.



Alternatively, use a copper or other conductive wire to connect the block of the left antenna input (the one with the braided cable) to pin 16. Again, press the reset button for 30 seconds, press the wire to pin 16 and the antenna block, and press the reset button for another 30 seconds.



You may experience small sparks with these procedures. And you need steady, accurate fingers – the pins on the flash chip are very, very small.



If you miss the correct pins, you’ve probably just completed what is known as “the final nail in the coffin.”



Secrets of the JTAG, aka Time to Buy a New Router



If you research bricked routers at all, you’ll inevitably come across the so-called miracle cure known as the JTAG (short for Joint Test Action Group, which is all about testing circuits). With the JTAG, you can supposedly revive nearly any dead router, not to mention the fact that (apparently) it slices, dices, chops and purees.



However, the JTAG is complicated. You need to build or buy a special cable. It may involve soldering. It connects your PC’s parallel port to circuitry inside your router. It is a very slow communications channel and can take hours of time from beginning to end. And it still may not work, despite the claims.



The JTAG poses the question, how much of a hacker are you? If the idea of building your own cable and connecting it to the guts of the router sounds incredibly cool, then by all means follow this link to the Google search for “hairydairymaid jtag” and follow the results. Otherwise, this may be the time to accept your loss and proceed through the stages of grief: anger, acceptance, and buying a new router.

How to Repair a Dead Linksys Wireless Router Page 2

It’s Dead, Jim!




Despite best — or not-so-best — efforts, accidents happen. Maybe your flash upgrade failed, or your router’s memory became corrupted. You may have made a mistake somewhere in the process. It could have been buggy firmware itself. After all, these open source replacements come with no guarantees. The time for blame has passed.



You’ll know your router has been bricked because, well, it no longer works. More specifically, you will probably see the power light blinking steadily. You may see most of its other lights lit solid.



If your router has a “DMZ” (define) light, note whether it is lit at power on or whether it lights a few seconds later, or never at all. This information could be useful soon.



Sometimes you can breathe new life into your bricked router. It is difficult to say exactly how often bricked routers are successfully revived, but it happens often enough that a number of resurrection techniques have emerged. There is no guarantee, of course, that any of these will work.



The methods devised by the networking community basically fall into two categories: gentle and desperate.



The more popular gentle recovery techniques involve establishing basic network communications with your router through software, followed by reflashing back to known, good firmware.



The desperate recovery techniques involve opening your router and attempting to physically reset its circuitry.



Gentle Recoveries



If you could simply reflash your seemingly dead router with an official Linksys firmware, you could, like Cher, turn back time. Not surprisingly, this is Linksys’ approved recovery method for Windows users, and the only one that won’t void your warranty – if it works.



To test if your router is only “a little bit dead,” you need to see if it responds to pings. First, reset your router to its factory default settings. Do this by powering it on and depressing the reset button for at least 30 seconds. You need the tip of a pen, or better yet, the pointy end of a pen cap to keep the recessed button depressed. The router’s lights will cycle off and back on after it reboots itself.



Using a computer with a wired Ethernet connection to one of the router’s LAN ports, open a command prompt in Windows (go to the Run command in the Windows Start menu, type "cmd" and then hit Enter). Use the ping command to see if the router responds at its factory default IP address, 192.168.1.1.



>ping 192.168.1.1

Pinging 192.168.1.1 with 32 bytes of data:

Reply from 192.168.1.1: bytes=32 time<10ms TTL=128

Reply from 192.168.1.1: bytes=32 time<10ms TTL=128



If you see something like the above, your router is not really dead. You may now dance a happy jig.



If, instead of “Reply from” you see “Request Timed Out” or “Hardware Error” or “Destination host unreachable,” your router is not responding. Do not dance a happy jig, and don’t bother with the rest of this Linksys-approved recovery, because you’ll just be wasting your time. Jump to the next section.



To proceed with the Linksys recovery, visit their Web site to download the latest official firmware. Select your router model from the drop-down list. Be sure to choose the exact model number marked on the underside label of your router – the WRT54G, for example, comes in versions from V1 to V6 (if unmarked, you have a V1).



Click the “Firmware” icon and proceed to download the firmware executable (.exe) file (define).



Force your network adapter into 10Mbps half-duplex mode. Because the procedure varies on different Windows versions, consult this Linksys support page for step-by-step instructions.



Launch the executable file you downloaded. Click “Next” on the splash screen. Set the “Router’s IP Address” to 192.168.1.1 and the “Router’s Password” to admin. Click “Next” again, and the firmware upload process begins.



About two minutes later, the update will complete, the router will reboot, and you’re back in business. At this point, you may revisit upgrading the firmware to an open-source replacement, but be sure to consider what may have gone wrong before, so as not to simply repeat your router’s near-death experience.



The Ping, Dear God, I Beg Of You Technique



If you router did not respond to pings at 192.168.1.1, it isn’t in great shape. But all hope is not yet lost.



Earlier, did you notice if the “DMZ” light on the front panel glows a few seconds after applying power? If yes, you may be able to reset the router to a failsafe mode. Cycle the power to your router and, as soon as DMZ lights up, depress the reset button for two seconds. It may take some coordination to pull this off accurately. Try again to ping the router.



If your firmware is truly hosed, your router may only respond to pings at 192.168.1.1 for a very brief window upon power-up. The moment power is applied, the router hasn’t yet loaded its firmware and is operating on a kind of BIOS. It is during this fleeting moment that you may be able to “catch” the router while still momentarily conscious, just before its brain-dead firmware is loaded.



You need to test whether your router is indeed responsive, even if just for a second, because that is all that's needed to breathe new life into it.



First, connect both your computer and your router to a hub (define) or switch (obviously, the switch built into the router doesn't count). If your computer is wired directly to your router, your Ethernet link may drop when the router is non-responsive, and you could miss the brief moment when it blinks its eyes awake. The hub/switch will keep your link up.



Second, manually configure your wired network settings. Assign your computer the IP address 192.168.1.10 (the last digit should be any number greater than 1), with subnet mask 255.255.255.0, and gateway 192.168.1.1.



Third, open a command prompt in Windows, or a terminal in MacOS X or Linux. Windows users should type:



ping –t 192.168.1.1



The “-t” switch in Windows will keep the ping running indefinitely.



MacOS X or Linux users should type:



ping 192.168.1.1



Your computer will continuously lob pings at the router. Now, cycle power to the router. You’re looking for any sign of life at all – does the router respond to any ping? Depending on your ping command, a successful reply may say “Reply from…” or “XYZ bytes from…” along with information like “time” and “TTL”.



If you do see even one or two replies, you’re set! This verifies that your router experiences a moment of consciousness.



If your router does not respond to a ping within a few seconds of powering up, it isn’t going to happen.

How to Resurrect a Dead Linksys WRT54G Router Part1

One of the more exciting developments for networking enthusiasts has been the evolution of open-source firmware replacements for certain popular, inexpensive routers (usually the famed Linux-running Linksys WRT54G).




While replacement firmware offers the promise of significantly expanded features, greater customization and mondo-tweakability, it also carries some risk. Should misfortune strike, you might, oh, let’s say, render your router into a useless hunk of plastic. Or, as victims prefer to say, you could “brick it.” How does a router become a brick? And if it does, is there any hope of bringing it back to life?



The short answers: "by accident," and "yes... sometimes."



How a Router Becomes a Brick



Bricks are very good at holding up the walls of your house. Bricks are not very good at routing network traffic. You don’t want your router to suddenly become one. (Likewise, you don’t want the bricks in your walls to suddenly become routers – although that would be pretty cool, no?) But sometimes it happens. Often, you can avoid this fate by understanding how a router can become a brick.



There is an alchemy to turning a router into a brick. The most common formula is the bad flash. When you upgrade the firmware in your router, you’re basically swapping in a new brain in place of the old. This brain controls most of the router's cognitive functions.



The upgrade process, described in The Open Source WRT54G Story, can require up to two minutes. If "Something Bad" happens during this process – loss of power to the router, loss of network connectivity to the uploading PC – you may have just bricked your router.



When upgrading your firmware, try to prevent "Something Bad" from happening:



•Be sure the power source is secure.

•Only upgrade through a wired Ethernet connection; do not use a wireless connection.

•Be sure to manually configure the IP address on your uploading PC – do not rely on automatic DHCP address assignment.

•Be sure to disable any software firewall running on your uploading PC, including the Windows firewall.

RAM, Corrupted



Your router has a small amount of on-board NVRAM (define), or non-volatile memory. Sometimes your flash upgrade will be successful, but your NVRAM will become corrupted. Often, this happens when the firmware you uploaded to the router wasn’t exactly the right version for your model. Be sure to read the upgrade instructions for your chosen firmware very, very, very carefully.



For example, consider DD-WRT, one of the most popular open source firmware replacements for Linksys WRT series routers. DD-WRT is available in many flavors. There is a “minimal” build with only a base feature set. There is also a “generic” build which lacks optimizations, and some model-specific builds, among other variants.



When upgrading the router from the Linksys-branded firmware, you are supposed to “step up” by first installing the minimal DD-WRT build, and upgrading from there to a more feature-rich build.



However, when upgrading your router through DD-WRT’s Web interface, you're directed to use the generic build.



Trip up on one of these finer points, and your upgrade may appear successful at first. But then you configure the router, it reboots, and hello Brickville, city of bricks. Most likely, your “successful” flash upgrade produced corrupted NVRAM.



You will always find message board threads by those who have disobeyed the upgrade instructions without dire consequences. These people can also eat pizza for three meals daily and never gain weight, and smoke a pack a day until they’re 98 years old. In fact, they often smoke and eat pizza while upgrading their routers. But the rest of us – we're not like them. Just follow the instructions, carefully.

Router Recover from a bad flash or Dead like wrt54g, wrt54gl ...

Recover back your Routers like wrt54g, wrt54gl and many other Router
So, you're afraid you've bricked your router. Don't worry, there are a number of things you can try to get your router working again before giving up and living with the fact that your router is now a paperweight.

It is also unfortunately possible to configure your router in ways which make it dead to the world. These techniques may be useful in these cases also.

Before you continue below, make sure you've first tried a hard reset to revive your router:




1.Disconnect the router from UTP cables (not the power cable).

2.Push reset button for 30 secs.

3.Without releasing reset button, disconnect power cord.

4.Hold the reset button for another 30 secs.

5.Replug the power cord.

6.Still hold the reset button for another 30 secs.

7.Release the reset button and give the router about 10 secs to resettle.

8.Disconnect power cord for another 10 secs and then reconnect.

9.All should be in default settings now.

This procedure is usually called 30/30/30 reset.



If the power light blinks in a neverending way, the 30/30/30 reset has no effect. Go to the Windows section of this page to see the reset-from-scratch procedure

Dual Wan DHCP Tomato with Round Robbin Loadbalancing

TODO


* Implement QOS on WAN2 (help?)

* WAN Failover

* DNS Failover (server doesn't appear to switch when an interface is down.)

* VPN testing



Change Log

ver. 0.1 - Modified w2.evt script to account for DNS route and disabled interfaces.

ver. 0.5 - Added iptables rules to preserve routes across connections, saved previous settings to properly remove rules/routes.



Useful info:

"RTNETLINK answers: No such process" means ip route cant find the interface "RTNETLINK answers: file exists" means there is already an overlapping entry in the routing table



I use the following at the beginning of my scripts to paste them into putty:



scrName=fullPathToYourScript

echo "" > $scrName

vi $scrName

:set noautoindent

i

Then just type: `Esc` :wq `Enter`









Preface

I have been working on a dual wan setup for Tomato for a while now and have compiled and modified a few scripts from various sources. This setup enables a second wan on port 4 of the router configured for DHCP (PPPOE is possible with modifications to the script). QOS is only applied to the primary WAN (i.e. WAN2 no QOS). I haven't tested to see what effect port forwarding has as that has not been a priority of the project. This works on a Asus WL-500GPv2 running the following flavor of Tomato:



* tomato-K26USB-1.27.9047MIPSR1-beta16-Ext

available from: http://tomatousb.org/ (Thank you teddy_bear.)

Of course you are modifying your router so the standard disclaimer applies... it is possible you can brick your router, use at your own risk, however I haven't bricked one beyond recovery...yet. I recommend running the w2.init script from the command line first, before you add any lines to the Administration, Scripts web interface, this way a simple power cycle will restore the routing table and firewall if you run into problems, if you mess up the nvram port settings then look into router reset / recovery, unless of course you implemented the safeguard mentioned in the Removal section.

This is a multi step process where first the new interface is created and then scripts are added to the 'Firewall' and 'WAN Up' scripts. Since the firewall and routing table is flushed and rebuilt every time the WAN comes up.



Prerequisites

* 2 wan connections

* jffs enabled and formatted.

* open port 4 on the router for wan 2 (you can change this)

* wan 1 is connected to WAN port

* Console access to router (ssh, telnet, etc...)







Removal

(This is first just in case...)



■as a safety precaution you may want to put this into the 12 second plus button script in case something goes wrong.

Remove the w2.init and w2.evt scripts from Firewall and WAN Up respectively and run the following in a console:



nvram set vlan0ports="0 1 2 3 5*"

nvram set vlan1ports="4 5"

nvram unset vlan2ports

nvram unset vlan2hwname

nvram unset wan2_iface

nvram unset wan_weight

nvram unset wan2_weight



#the following is optional and will remove all scripts from the Firewall and WAN Up... you are warned.

nvram set script_fire=""

nvram set script_wanup=""



# or if you stored your scripts as illustrated this will preserve your other scripts... I like this one better

nvram set script_fire=`nvram get script_fire
grep -v jffs/wan2/w2.evt`

nvram set script_wanup=`nvram get script_wanup
grep -v /jffs/wan2/w2.init`



nvram commit



#for completeness delete the scripts folder

rm -r /jffs/wan2

Setup Dual Wan Round Robbin Loadbalancing

First Create your 2nd wan interface: vlan2 on port 4



■Ports are labeled in reverse order i.e.

Box label: WAN 1 2 3 4

Nvram label: 4 3 2 1 0



some of the newer routers may have different internal assignments, so you may want to run



nvram show
grep vlan.ports

and examine the output... before modification mine looks like:



vlan0ports=1 2 3 4 5*

vlan1ports=0 5

Using the console:



nvram set vlan0ports="3 2 1 5*"

nvram set vlan1ports="4 5"

nvram set vlan2ports="0 5"

nvram set vlan2hwname=et0

nvram set wan2_iface=vlan2



#the following adjust the Round Robbin weighting of each respective interface

nvram set wan_weight=1

nvram set wan2_weight=1



nvram commit



mkdir /jffs/wan2

Using the console and your favorite text editor create the following script and save it to:

/jffs/wan2/w2.init



#!/bin/sh

# script to bring up the secondary wan interface



ModName="WAN2 init: "



runscr="/jffs/wan2/w2.evt"

iface=`nvram get wan2_iface`

lanhost=`nvram get lan_hostname`



#logger $ModName killing old: `ps

ifconfig $iface up

ip=`udhcpc -i $iface -s $runscr -H $lanhost
grep Lease
awk '{print $3}'`

#ifconfig $iface up $ip



logger $ModName complete: $iface $ip

Using the console and your favorite text editor create the following script and save it to:

/jffs/wan2/w2.evt



#!/bin/sh

# Dual Wan Script for Tomato

# Purpose: insert the firewall and route entries, update DNS for wan2

# ver. 0.5

# Wan 2 is DHCP

# the following entries exist in nvram and are configured properly ( name(default value) ):

# lan_ifname(br0)

# wan_iface(vlan1)

# wan2_iface(vlan2)

#

# *use these values to adjust the round robbin weighting for each wan:

# wan_weight(1)

# wan2_weight(1)

#

# vlan0ports(3 2 1 5*)

# vlan1ports(4 5)

How to install DD-WRT firmware on Linksys WRT54GL Wireless Router and receive wireless singnal

This tutorial will show you how to install the DD-WRT firmware on a Linksys WRT54GL wireless router.  The DD-WRT firmware makes advanced features, usually only available on more expensive routers, available on cheaper models.  My purpose for this mod is to create a wireless receiver for my modded Xbox.
Hardware you will need:

• Linksys WRT54GL wireless router
• PC
• Ethernet cord

Software you will need:

• Internet Explorer
• DD-WRT Version 23 SP2 Mini
• DD-WRT Version 23 SP2 Standard
• Compression application (Winzip, WinRAR, etc.)

The easiest way to install the DD-WRT firmware on a Linksys WRT54GL wireless router is using the firmware upgrade option in the Linksys web interface. In order to install DD-WRT on version 1.0 of the router, the mini version will first have to be installed, then the standard version. Determine your version here.

**DISCLAIMER** The following instructions will void your warranty and if done incorrectly may brick your router. I can not be held responsible for any resulting equipment failure or otherwise undesirable results. Proceed at your own risk.

 Linksys Wireless Router Hack ....-.

Install DD-WRT Version 23 SP2 Mini:

1. Disable all firewalls, anti-virus software, and wireless connections on the PC
2. Unzip the DD-WRT Version 23 SP2 mini and standard compressed files
3. Connect the PC to the WRT54GL via Ethernet cable (ports labeled 1-4, not the WAN or Internet port)
4. Open Internet Explorer and navigate to 192.168.1.1 (this will open the Linksys web interface)
   NOTE: You will be presented with a login prompt, use the credentials you set when configuring the router, if you cannot remember what they are, press the Reset button for 30 seconds, username and password will be reset (username: (blank), password: admin)
5. Select the Administration->Factory Defaults tab
6. Select the Yes radio button in the Restore Factory Defaults: section and press the Save Settings button
7. Press the OK button on Warning prompt
8. A success screen will appear followed by a login prompt (username: (blank), password: admin)
9. Select the Administration->Firmware Upgrade tab
10. Press the Browse… button and navigate to the location which the mini version of DD-WRT was unzipped
11. Select the dd-wrt.v23_mini_generic.bin file and press the Open button, then the Upgrade button
    NOTE: Do NOT do anything on the computer while the upgrade is taking place, a failed upgrade can brick your router
12. Press the continue button on the success page
13. The login prompt will appear again (username: root, password: admin) but login should FAIL
14. Verify that the router is working by pinging it (go to Start->Run, type cmd, press Enter, type ping 192.168.1.1, press enter, should be successful)
15. If router is working, press and hold the Reset button on the back of the router then unplug the power to the router
16. While continuing to hold the Reset button, plug in the power to the router and hold the Reset button for 30 more seconds
17. When the Power LED on the router stop blinking, open Internet Explorer and navigate to 192.168.1.1, you may be prompted to login (username: root, password: admin)
18. DD-WRT mini web interface should now be displayed

Install DD-WRT Version 23 SP2 Standard:

1. Repeat steps 1-9 from above
2. Press the Browse… button and navigate to the location which the standard version of DD-WRT was unzipped
3. Select the dd-wrt.v23_generic.bin file and press the Open button
4. Select the Default settings radio button in the After flashing, reset to section, then press the Upgrade button
   NOTE: Do NOT do anything on the computer while the upgrade is taking place, a failed upgrade can brick your router
5. A success page will appear followed by the DD-WRT standard web interface

If something goes wrong when flashing the firmware and your router is not working, all may not be lost. Read on here to try and resurrect you router.

You can use wireless router with DD-WRT as a wireless adapter for Xbox free

This tutorial will show you how to use a wireless router with the DD-WRT firmware installed as a wireless router for and Xbox or Xbox 360.
Hardware you will need:

• Wireless router with DD-WRT firmware installed (Client)
• Wireless router (Host)
• Xbox or Xbox 360
• PC
• Ethernet cord (optional)

Software you will need:

• Internet Explorer

You will have to configure the the Client router to be a wireless receiver which will allow it to receive the wireless signal from the Host and bridge it to the 4 Ethernet ports on the router. I chose to do this rather than purchase an Xbox wireless adapter because I could purchase a router (~$50) for around half the cost of the Xbox wireless adapter (~$100). This tutorial assumes you are using a Linksys WRT-54G/GL/GS router as the Host and an internet service provider (ISP) that provides a dynamic IP via DHCP.
Obtain Host router info:

1. Connect PC to Host router via Ethernet cord or wirelessly
2. Open Internet Explorer and navigate to 192.168.1.1 (this will open the Host router’s web interface)
   NOTE: You will be presented with a login prompt, use the credentials you set when configuring the router, if you cannot remember what they are, press the Reset button for 30 seconds, username and password will be reset to factory defaults (username: (blank), password: admin)
3. Select the Setup->Basic Setup tab and save the Host router’s Local IP, Subnet Mask, and Starting IP Address (usually 192.168.1.1, 255.255.255.0, 192.168.1.100)
4. Select the Wireless->Basic Wireless Settings tab and save the router’s SSID
5. Select the Wireless->Wireless Security tab and save the security info, if used
6. Select the Status->Router tab and save the DNS 1, and DNS 2 values

Configure Client router to receive wireless signal:

1. Connect PC to Client router via Ethernet cord or wirelessly
2. Open Internet Explorer and navigate to 192.168.1.1 (this will open the Host router’s web interface)
   NOTE: You will be presented with a login prompt, use the credentials you set when configuring the router, if you cannot remember what they are, press the Reset button for 30 seconds, username and password will be reset to factory defaults (username: root, password: admin)
3. Select the Wireless->Basic Settings tab
4. Change Wireless Mode to Client, change Wireless Network Name (SSID) to value saved from step 4 above, then press the Save Settings button
5. Select Wireless->Wireless Security tab
6. Enter wireless security settings from step 5 above and press the Save Settings button, if applicable
7. Select Setup->Basic Setup tab
8. Change Internet Connection Type.Connection Type to Static IP
9. Change Internet Connection Type.Internet IP Address to 192.168.1.2 (or any IP between Host’s Local IP (192.168.1.1) and Host’s Staring IP Address (usually 192.168.1.100))
10. Change Internet Connection Type.Subnet Mask to value from step 3 above (usually 255.255.255.0)
11. Change Internet Connection Type.Gateway to Host router’s Local IP from step 3 above (usually 192.168.1.1)
12. Change Internet Connection Type.Static DNS 1 to Host router’s Local IP from step 3 above (usually 192.168.1.1)
13. Change Internet Connection Type.Static DNS 2 to DNS 1 value from step 6 above
14. Change Internet Connection Type.Static DNS 3 to DNS 2 value from step 6 above
15. Change Router IP.Local IP Address to 192.169.2.2
16. Change Router IP.Subnet Mask to 255.255.255.0
17. Change Router IP.Gateway to 192.168.2.2
18. Change Router IP.Local DNS to Host router’s Local IP from step 3 above (usually 192.168.1.1)
19. Press the Save Settings button, you will get Settings are successful screen, then press the Close button
20. Go to Start->Run, then type cmd, and press Enter
21. Type ipconfig /release, then press Enter
22. Type ipconfig /renew, then press Enter
23. Open Internet Explorer and navigate to 192.168.2.2 to make sure the settings are saved
    NOTE: notice the new IP address for the Client router, it will be the value specified in step 15

Any device plugged into the Client router’s ports labeled 1-4 will now be able to connect to the internet. The Client router’s wireless signal will not be visible to any wireless adapter.
If you have a modded Xbox running Xbox Media Center (XBMC) connected to the Client router and wish to connect to a shared folder on a PC connected to the Host router, you may have to connect by entering the IP address of the PC sharing the folder rather than browsing to the PC.
