Hey.
I found a cisco aironet 350 card and latest NOV28.2006 miboot image recoginzed it.
I successfully connected powerbook 5300cs to the wifi router with iwconfig/dhclient.
However, aironet card has errors on the interface (eth0)
It was possible to connect via ssh to local network computers, do wget of my provider's homepage, but not google, or some other pages.
Resolving works, wget, telnet to 80 port - not.
I wonder whether there is a necessary firmware installation?
Anyway, I decided to try newer kernel, 2.6.31, and it didnt boot:
