Wifi has been out of operation since I started Knoppix w/CNet USB Dongle plugged in. The CNet icon still comes up along with Kwlan icon every time I boot up. What files do I need to look at in regards to wifi settings? I can not make any changes using the KWlan gui. (I had been running the laptop on an Xubuntu HDD which works w/the CNet USB wifi dongle. I forgot to remove it and plug in the Netgear card that works w/Knoppix.)
