Hi all;

I'm getting wildly inconsistent results... when I first connected to the 
wireless at a client site today I got speeds up to 25Mbps!

Later the wireless disconnected and then cycled through asking me for 
the password over and over and never connecting... since then the few 
times I did get connected I could not even go to a web page, it tried 
for awhile then disconnected again

Any help debugging this would be appreciated.  In the meantime, does 
Fedora play well with USB wireless cards/devices? would it be worthwhile 
to grab a USB wireless card while I try and work through this?


Thx
