Yes.I have the same problem. I have 2 pci cards from Asus (nx 1001 but one is on realtek, the other is on ics/ipc sundance); Both of them works fine on Ubuntu 11.10, but i don't know why it doesen't work at 12.04. I see that there are present in ifconfig -a, i see them on taskbar but there is no connection. As soon as i log in i see "connection lost" or "wired network not connected" (or something like that, i forgot the exact word for it).

My outputs:

ifconfig
