First of all, thanks goes to "UnderScore" for providing information, commands and steps.

This is my 2nd day messing around with Knoppix 5.0 and linux overall and I've managed to get my wireless Netgear WG311T (108 MBps) card worknig. Here's how I did it and it's really simple.

Step 1: Record your WEP key (Hex key not ascii) and note what security mode it's set to: Open or Restricted (For this example, it's set to Open)

Step 2: Open up KwifiManager under Knoppix > Network/Internet > KwifiManager (Wireless Lan Manager)

Step 3: From KwifiManager Interface select > Settings > Configuration Editor

Step 4: Check the box "Use encryption" then next to it click "Configure"

Step 5: The option "Crypto Mode", select which security mode you chose, for this example I select Open.

Step 6: Under "Crypto Keys" > Key 1 > type in your Hex code

Step 7: Hit "Ok", "Apply" then click on "Activate" Wait a moment and it should pickup your Router's Signal

Step 8: Click on Konsole > type this command into the konsole > netcardconfig

Step 9: Select your Wireless device (in this case it's ath0),
when prompt "Use DHCP Broadcast" Click Yes, it shoud config your settings for you.

Step 10: If all went well you should attain an Local Ip and be able to surf the net now.

Note: For Step 9 if you can't select your device then open up konsole then type in the following command:

sudo kwrite /usr/sbin/netcardconfig

Once that is done, find the line code:
NETDEVICES="$(cat /proc/net/dev | awk -F: '/eth.tr.wlan.:/{print $1}')"

and input ath.: between "eth.:" and "tr.:" so your code should look like this:
NETDEVICES="$(cat /proc/net/dev | awk -F: '/eth.ath.tr.wlan.:/{print $1}')"

Save and exit and repeat Step 9.

If you still get an error but you're Kwifimanger says you're connected but no local ip that usually means that you have set your WEP key wrong. Please read the steps carefully. Thank you.


PS. Off topic but when I connected to Networkd Neighborhood and browse my 2nd computer (XP PRO) I was able to search everyfolder and not just the shared only folders, which is cool.
