Thanks for your help so far.  Yes, I have looked at the handbook section 
on wireless, and as a matter of fact I installed 8.1 on an ancient 
Compaq Presario (6GB HD!) and was able to configure the Atheros wireless 
pci card so that the computer works quite well.  OK...the info I gleaned 
from pciconf -lv shows:

device    = 'driverIntel PRO/Wirelss 220BG  (MPC13B'

Cheers...
