Newbie - Wireless LAN

Hi folks. Newbie here. I've just got the Knoppix and I would like to run it on my laptop - Dell Inspiron 1300. I need assistance in making it connect to the Linksys Wireless Router SSID: Boyette, Channel: 6, KEY: 50228cffa6.
I tried using the WaveLan thing. I entered in all the information that I knew, but some of the parameters it gave me the option to put I didnt know so I left blank. The laptop has the Dell Wireless 1370 WLAN internal card and works OK on Windows.
Any assistance on how to configure would be greatley appreciated!
