Wireless connectivity NOT resolved

Richard,

what card are you using? I'm running the internat IPW2100 card (Intel stuff) 
on my ThinkPad. It started to work fine after I got the firmware downloaded 
and installed correctly.

To get it going I used the GUI netconfig tool (Under System Tools -> Network 
Device Control in KDE). I set up the key and all that stuff there. Be careful 
to use the right number of characters for WEP. the 64-bit WEP used 5 bytes 
(actually only 40 bit encryption). The 160 bit (I think that what it is) uses 
13 bytes for encryption.

Since the card works without WEP, my initial thought of checking your MAC 
filtering on the WAP would be a moot point, but I mention it anyway. 

Also, make sure that you're actually talking to your WAP and not some other 
thing that one of your neighbors uses.

Best regards,
Chris
