Title:
No stable wireless connections

Bug description:
$ lspci | grep Wireless

Network Adapter (PCI-Express) (rev 01)
$ uname -r
2.6.32-16-generic
My wireless connection is very unstable. Network-manager has to
reconnect every few seconds. I tried it on a few WPA (2) networks and
it's the same on each. I also tried 2.6.33 from Ubuntus mainline
Kernel repository and it had the same problems.
