Reassigning to the 'linux' package; NetworkManager only does the establishing of the connection, everything else (including pushing bits around), is done by the driver.

Seems random, but often enough that copying a folder of music stalled every 5 or 6 songs, and a folder of video, about two or three times per video. No other linux machine here has this problem. Admittedly the others are still on Ubuntu 10.10, but I tested a transfer of 4 gigabytes of data on the Ubuntu 10.10 laptop with an AR9285 without any issues. Nothing is reported to dmesg and the problem fixes itself temporarily if I disconnect/reconnect in network manager or toggle the wifi kill switch. By toggling the kill switch I was able to successfully copy over 4 gigabytes of data, with perhaps 15 reconnects. I was hoping one of the workarounds in bug #761176 would help, but none of them seemed to do the trick, I get the feeling there were a few problems reported in that bug, and since it was closed out fixed, filed a new one. I've tested the 2.6.37 kernel, and 2.6.38 6-10 as well as -11 proposed. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/761176/comments/20 appears to have similar hardware, although I don't know if the problem is the same. 02:00.0 Network controller: Atheros Communications Inc.
