I have an IBM ThinkPad with an Atheros/IBM mini-PCI wireless card. In Knoppix ver 3.9 (CD), I was able to login to my wireless router by opening a terminal and entering the following code:

su
iwconfig ath0 essid mynetworkssid
iwconfig ath0 enc myweppassword
pump -i ath0

This doesn't work in ver 4.0.2 (CD). The first iwconfig command returns "ath0 - device not found".

Anyone have a fix for this ? Thanks !
