Hi,
I've gotten my Dell 600m laptop ( Centrino based ) to work with Knoppix 3.4 . One first thing to mention is that kernel 2.6 will not work. The module for Intel 2100 pro wireless isn't working and returns a funky error message when I tried to load it with 'modprobe'. So, use the default 2.4.26 kernel . The steps I am posting are from what I remember from yesterday night.

1. open a terminal and keep it open for step 2 and 5. ( optional ) and step 6. ( needed )

2. optionally, type 'iwconfig'. You now should see a eth0 device which points to the wlan card.( you may also do a 'lsmod' to see whether a module ipw2100 has been loaded )

3. now run the wlan configuration tool. You will start it from the desktop and not from the terminal. It comes with a GUI so it makes it a little less cryptic. You will find it under start - knoppix - internet ( not 100% sure about that order but you'll find it by clicking around )

4. You now got to know your WLAN setup parameters like ssid / channel and encryption key. That's because you got to enter them when prompted. Forget about entering extra info you don't know, you won't need it ( like module parameter ). When you are somewhat sure that everything is fine and the wlan config tool exit without any error, you most likely are ready to go except that you now need to start DHCP on eth0.

5. Optionally type again 'iwconfig'. Now, you should see an updated table for 'eth0' which should show you the correct SSID which you assigned when setting up the wireless router. BTW, I have not setup a SSID requirement for my wlan network but I have a encryption key. I can still see the SSID correctly retrieved.

6. As a final step, type 'netcardconfig'. Pick 'eth0' and if asked to start dhcp say yes. Exit the tool. To verify that you got finally a network running, type 'ifconfig' . You now hopefully see a device 'eth0' added ...

7.DONE.

Hope that helped. Forgive me if I missed or misspelled a configuration step. As I said I am typing this from my memory.

Dan.
