[ltp] Connecting a T42 Intel WiFi 2200BG to a Linksys WRT54G

[Konstantin Filtschew]

hi,

I use the newer 2915ABG, but should be the same, because it's the same
driver.

Give us your configuration of the WRT54G. 

For preshared key with WEP, try this:
iwconfig eth1 essid <your essid> mode managed channel <your channel> key
<your preshared key>
dhclient eth1

For WPA, you have to install wpa_supplicant and setup
wpa_supplicant.conf:

---------- wpa_supplicant.conf ----------------------------------
network={
        ssid="<your essid>"
       
        # You have to use the long preshared key, not the password
        # you can generate this with the command:
        #  wpa_passphrase <ssid> <passphrase>
        psk=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
   
        
}
---------------- that's all -------------------------------------

This is the way you start the connection:

iwconfig eth1 essid <your essid> mode managed channel <your channel>

# For better debugging, you can add: -dd to wpa_supplicant command
wpa_supplicant -i eth1 -c /etc/wpa_supplicant.conf -D ipw -B

Your access point must be visible for this.

I think your problem is the passphrase,  that you setup on your linksys.
Try to use the preshared key, because the passphrase can make problems!


I don't like KDE and SUSE, for this setup you have to ask someone else,
I can only give you the commands to setup it for script use and with a
little bit fun, you can write a script to toggle between wlan and
network. Yes it's faster and easier then windows use :)

For further help, contact the list, I'll try to help.

Building an operation system without source code,
