Description:

I have a WNA1100 WiFi dongle:
ID 0846:9030 NetGear, Inc. WNA1100 Wireless-N 150 [Atheros AR9271] (ath9k_htc)
Sometimes while I'm playing, my Internet connection is broken.
When I'm disconnected, I need to reboot my computer. If not, I'm unable to connect to my Internet box.
systemd-journalctl gives me many errors (cf log file).

It started 20 days ago when I updated to 3.6.10 or 3.6.11. I also updated following pachages on Archlinux:
[2013-01-08 13:25] upgraded cronie (1.4.9-1 -> 1.4.9-2)
[2013-01-08 13:25] upgraded desktop-file-utils (0.20-1 -> 0.21-1)
[2013-01-08 13:25] upgraded dhcpcd (5.6.3-2 -> 5.6.4-1)
[2013-01-08 13:25] upgraded iptables (1.4.16.2-1 -> 1.4.16.3-1)
[2013-01-08 13:25] upgraded mpfr (3.1.1.p2-1 -> 3.1.1.p2-2)
[2013-01-08 13:25] upgraded nss (3.14.1-1 -> 3.14.1.1.93-1)
[2013-01-08 13:25] upgraded pango (1.32.4-1 -> 1.32.5-1)

Currently running 3.7.4 but I had this bug with 3.6.11.

Hard to reproduce because it's very random. But it happens one time per day.

I opened a bug on Archlinux: https://bugs.archlinux.org/task/33617

Just found this while trying to triage a similar issue (both with the WNA1100 and a TP-Link AR7010 device); ath9k_htc instability seems endemic and there are lots of reports to this effect.

Hughes: you mention you used to have a working kernel?  Do you know what it was?

Hi,
This bug became really strange. When I'm using Internet and working on my computer, everything seems to be fine.
But when I start to play a specific game called "Heroes of Newerth", the bug appears and sometimes my dongle is simply restarted. I don't remember being disconnected while I was working.
Tried with an other dongle (HWGUSB2-54-LB with rt73usb) and it disconnected once.
So, I don't know what's going on and where the bug is located.

I cannot tell you what kernel is working (it's been a long time and now I'm with 3.8.8) but kernels before 3.6.10 or even 3.6.9 should be ok.

is still reproducable with latest kernel and firmware from git?
