Setup wireless connection with wep and knoppix 3.6

Posted on 2004-10-29
Last Modified: 2012-06-22
I have a laptop running knoppix for fun with a orinoco gold card. I have no problem getting on a non-secured network because knoppix automatically configures everything on bootup. I took my laptop to work where we have a secured network and I know the wep key. I don't know how to configure my connection to get onto the secured network. I have the wireless toolkit installed with knoppix and I have no problem getting on at home or at a cafe, just at work. I would like to find a step by step guide or if all fails then someone to help me through setting up my nic to use a wep key to get on a network. I have some basic linux knowledge but it's limited.

    You should have the iw* commands available to you: iwconfig, iwlist, iwspy, iwpriv . The main stay of manupliating wireless settings from the command line is iwconfig. iwconfig is to wireless as ifconfig is to wired. Assuming that Knoppix uses wlan0 for you wireless card the commands look like this:

    To set your ssid (just in case):
    iwconfig wlan0 essid YOURNET_SSID

    To configure a wep key:
    iwconfig wlan0 key restricted YOUR_WEP_KEY

    To set a key other than the current use [index] before  the key:
    iwconfig wlan0 key restricted [2] YOUR_WEP_KEY2
    iwconfig wlan0 key restricted [3] YOUR_WEP_KEY3

    To set the active key:
    iwconfig wlan0 key [2]

    To turn wep on (you shouldn't need this, but just to be safe):
    iwconfig wlan0 enc on

    To turn wep off:
    iwconfig wlan0 enc off

    IIRC, you can combine iwconfig commands onto one line:
    iwconfig wlan0 essid YOUR_SSID key YOUR_WEP_KEY enc on

    Then, cross your fingers, you should be able to run your favorite dchp client utility or configure your ip and subnet manually. Check out man iwconfig for more info.
