    I had the same problem with Ubuntu and found the solution by entering the WEP key in hexidecimal in the Ubuntu wireless adapter configuration.

    I have a Dell Inspiron 4100 with an Orinoco Gold card that works flawlessly with Fedora but would not work with Ubuntu at all. I always enter the WEP key in XP and Fedora in ASCII but the AP and card will accept ASCII or hexidecimal.

    It finally dawned on me to try hexidecimal and it worked.

    If you're not deep into binary, hexidecimal, etc., you can convert the ASCII WEP key to hexidecimal here:

    Simply enter the ASCII string and click Translate. Copy the hexidecimal WEP key down and enter it into Ubuntu.

    Hope this helps and good luck with Linux.

      You can enter an ASCII password instead of a HEX string (fortunately, if you're using 128bit WEP...)

      Prefix the string with s: in the WEP Key field in the Wireless Settings. This doesn't seem to be officially documented anywhere at the moment, but it worked for me.

    Yes, WEP is turned on. If you tried to connect using wifi0, try the eth1 (eth0 is wired ethernet port).
