Hum not a quite good idea...

changing the ssid on the router to fit the one with knoppix is not a secure way for wlan...

I've just spent hours (like you) to figure how I can configure SSID in Knoppix for my dwl-650 and found the good options for wlanctl-ng, but I have no idea what to do next (what need to be relaunch, etc)

Maybe I will look for the disk with configuration options, but i'm not sure it will help.

If you know how to configure SSID in knoppix, I will be happy if you can share...
