[SATLUG] Continuing Wireless Problem

Is there any reason for using 64-bit Ubuntu other than to utilize 64-bit
from your hardware? Is your Windows XP installation 64-bit?

Chances are, you may want to try 32-bit Ubuntu and just go that route. Sure,
64-bit is fun, but unless you have more than 4GB of RAM, it's not going to
be all that helpful. Especially considering how much more support 32-bit
platforms have over 64-bit platforms.
