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.

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

grep -v grep
awk '{print $1}'`

kill `ps

grep -v grep
awk '{print $1}'`

ifconfig $iface down

sleep 5

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_iface(vlan1)

# wan2_iface(vlan2)

#

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

# wan_weight(1)

Best 4 Steps to Set Up Your Home Wireless Network.SETTING UP YOUR WIRELESS NETWORK ON LINKSYS

You can use a wireless network to share Internet access, files, printers, and more. Or you can use it to surf the Web while you're sitting on your couch or in your yard. Plus, it's easier to install than you think.

There are 4 steps to creating a wireless network:

For Windows XP users, Windows XP Service Pack 2 is not required for wireless networking, but it does make things much easier. Service Pack 2 also helps protect you against hackers, worms, and other Internet intruders.

1.	Choose your wireless equipment linksys-wireless-help.blogspot.com The first step is to make sure that you have the equipment you need. As you're looking for products in stores or on the Internet, you might notice that you can choose equipment that supports three different wireless networking technologies: 802.11a, 802.11b, and 802.11g. We recommend 802.11g, because it offers excellent performance and is compatible with almost everything. Shopping list • Broadband Internet connection • Wireless router • A computer with built-in wireless networking support or a wireless network adapter A wireless router The router converts the signals coming across your Internet connection into a wireless broadcast, sort of like a cordless phone base station. Be sure to get a wireless router, and not a wireless access point. A wireless network adapter Network adapters wirelessly connect your computer to your wireless router. If you have a newer computer you may already have wireless capabilities built in. If this is the case, then you will not need a wireless network adapter. If you need to purchase an adapter for a desktop computer, buy a USB wireless network adapter. If you have a laptop, buy a PC card-based network adapter. Make sure that you have one adapter for every computer on your network. Note: To make setup easy, choose a network adapter made by the same vendor that made your wireless router. For example, if you find a good price on a Linksys router, choose a Linksys network adapter to go with it. To make shopping even easier, buy a bundle, such as those available from D-Link, Netgear, Linksys, Microsoft, and Buffalo.For more info : linksys-wireless-help.blogspot.com . If you have a desktop computer, make sure that you have an available USB port to plug the wireless network adapter into. If you don't have any open USB ports, buy a hub to add additional ports.
2.	Connect your wireless router Since you'll be temporarily disconnected from the Internet, print these instructions before you go any further. First, locate your cable modem or DSL modem and unplug it to turn it off. Next, connect your wireless router to your modem. Your modem should stay connected directly to the Internet. Later, after you've hooked everything up, your computer will wirelessly connect to your router, and the router will send communications through your modem to the Internet. Next, connect your router to your modem: Note: The instructions below apply to a Linksys wireless router. The ports on your router may be labeled differently, and the images may look different on your router. Check the documentation that came with your equipment for additional assistance. • If you currently have your computer connected directly to your modem: Unplug the network cable from the back of your computer, and plug it into the port labeled Internet, WAN, or WLAN on the back of your router. • If you do not currently have a computer connected to the Internet: Plug one end of a network cable (included with your router) into your modem, and plug the other end of the network cable into the Internet, WAN, or WLAN port on your wireless router.linksys-wireless-help.blogspot.com • If you currently have your computer connected to a router: Unplug the network cable connected to the Internet, WAN, or WLAN port from your current router, and plug this end of the cable into the Internet, WAN, or WLAN port on your wireless router.For more linksys-wireless-help.blogspot.com . Then, unplug any other network cables, and plug them into the available ports on your wireless router. You no longer need your original router, because your new wireless router replaces it. Next, plug in and turn on your cable or DSL modem. Wait a few minutes to give it time to connect to the Internet, and then plug in and turn on your wireless router. After a minute, the Internet, WAN, or WLAN light on your wireless router should light up, indicating that it has successfully connected to your modem.
3.	Configure your wireless router Using the network cable that came with your wireless router, you should temporarily connect your computer to one of the open network ports on your wireless router (any port that isn't labeled Internet, WAN, or WLAN). If you need to, turn your computer on. It should automatically connect to your router. For more: linksys-wireless-help.blogspot.com Next, open Internet Explorer and type in the address to configure your router. You might be prompted for a password. The address and password you use will vary depending on what type of router you have, so refer to the instructions included with your router. As a quick reference, this table shows the default addresses, usernames, and passwords for some common router manufacturers. Router Address Username Password 3Com http://192.168.1.1 admin admin D-Link http://192.168.0.1 admin Linksys http://192.168.1.1 admin admin Microsoft Broadband http://192.168.2.1 admin admin Netgear http://192.168.0.1 admin password Internet Explorer will show your router's configuration page. Most of the default settings should be fine, but you should configure three things: 1. Your wireless network name, known as the SSID. This name identifies your network. You should choose something unique that none of your neighbors will be using. 2. Wireless encryption (WEP) or Wi-Fi Protected Access (WPA), which help protect your wireless network. For most routers, you will provide a passphrase that your router uses to generate several keys. Make sure your passphrase is unique and long (you don't need to memorize it). 3. Your administrative password, which controls your wireless network. Just like any other password, it should not be a word that you can find in the dictionary, and it should be a combination of letters, numbers, and symbols. Be sure you can remember this password, because you'll need it if you ever have to change your router's settings. The exact steps you follow to configure these settings will vary depending on the type of router you have. After each configuration setting, be sure to click Save Settings, Apply, or OK to save your changes. Now, you should disconnect the network cable from your computer. freewebpromotion
4.	Connect your computers If your computer does not have wireless network support built in, plug your network adapter into your USB port, and place the antenna on top of your computer (in the case of a desktop computer), or insert the network adapter into an empty PC card slot (in the case of a laptop). Windows XP will automatically detect the new adapter, and may prompt you to insert the CD that came with your adapter. The on-screen instructions will guide you through the configuration process. Note: The steps below only apply if you're using Windows XP Service Pack 2. If you're running Windows XP and you don't have Service Pack 2 yet, plug your computer into your wireless router anddownload and install Windows XP Service Pack 2. Windows XP should show an icon with a notification that says it has found a wireless network. Follow these steps to connect your computer to your wireless network: 1. Right-click the wireless network icon in the lower-right corner of your screen, and then clickView Available Wireless Networks. If you run into any problems, consult the documentation that came with your network adapter. Don't be afraid to call their tech support. 2. The Wireless Network Connection window should appear and you should see your wireless network listed with the network name you chose. If you don't see your network, click Refresh network list in the upper-left corner. Click your network, and then click Connect in the lower-right corner. 3. Windows XP prompts you to enter a key. Type the encryption key that you wrote down earlier in both the Network key and Confirm network key boxes, and then click Connect. 4. Windows XP will show its progress as it connects to your network. After you're connected, you can now close the Wireless Network Connection window. You're done. Note: If the Wireless Network Connection window continues to show Acquiring Network Address, you may have mistyped the encryption key. Foe more: linksys-wireless-help.blogspot.com
