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.
