Comment 200 for bug 414560

I have the similar problem on my laptop, ubuntu 11.04 and kernel 2.6.38-9-generic x86_64.

The ping to router failed again and again after several minutes running.
It's easy to reproduce in my env. Once I use bittorrent client to download something, after a while, the problem occurs.
I need to reconnect to my AP to get everything back.

05:00.0 Network controller: Atheros Communications Inc. AR9287 Wireless Network Adapter (PCI-Express) (rev 01)

If I use a USB wireless card instead, everything is fine.

Hope someone can fix this issue.
