Comment 272 for bug 401126

I just got a Thinkpad Edge yesterday and installed 10.04 beta1 x64 on it. Out of the box the driver was only seeing 1 unencrypted network. I grabbed the latest realtek driver and then was able to see the other networks (my own is WPA/Enterprise). After I deleted the original driver (from /lib/modules/<version>/kernel/ubuntu) and installed the new one, things seemed to be working OK.

But it looks like the driver stops working after the machine has gone to sleep and waken up again. It would see my network but failed on WPA authentication. rmmod / modprobe seemed to take care of that.
