$ lspci | grep Wireless
02:00.0 Network controller: Atheros Communications Inc. AR9285 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.

- No stable wireless connections + NM dis- and reconnects every few seconds on all WPA(2) networks; wicd + doesn't -- Atheros AR9285 |
After installung and using wicd, giving me a mostly stable connection, it occurs to me that this may be a bug in network-manager, not in the kernel. Thus, I marked network-manager as also affected.
I'm running network- manager{ ,-gnome} 0.8-0ubuntu2.
