Based on this, I know I have a Broadcom NetXtreme ethernet adapter (eth0
in my case) and a Broadcom BCM4312 wireless adapter (eth1 in my case).
modprobe -l shows a b43 module. But obviously it isn't sufficient for
the BCM4312.
eth0 works well (although DNS dies on a regular basis, for which there
are a lot of heated discussions about NetworkManager and dns on the
various linux sites). eth1 is not found and when I right-click on the
NetworkManager icon on the top right corner of the screen, it shows a
wireless in a grayed out text. When I go to
System>Administration>Network, I cannot enable the wireless (eth1)
device. It tries and then after trying to find an IP, it fails.
