Comment 31 for bug 414560

I just got a new work laptop a couple of weeks ago and have been having nothing but trouble with the wireless card.

02:00.0 Network controller: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01)

using the ath9k driver.

Depending on the access point I am using, I get a wide variety of results and stability.

At home I have a Buffalo WHR-HP-G54 with the Tomato firmware. It is "reasonably" stable, it disconnects every hour or so without cause which is far better than anywhere else I've used this.

At work I have had two different routers that I am unsure of models on, one was a NetGear and the other is a D-Link. With both I lose connection constantly and have to reassociate. This happens at least once every half hour.

At another location I have a Linksys WRT54GL. It is almost completely and utterly unusable. The wireless never disassociates, it just stops working completely. I have to manually re-associate with the access point for the connection to start working again.

On the Linksys it is really strange because some services continue working while others just die, and eventually they all die. And this happens multiple times every half hour. Often I don't even have a connection the instant I connect to the access point.

This is REALLY bad. Atheros cards have been available with an open source driver for a long time and there are tons of open bugs in Launchpad about this same kind of issue with the ath9k driver.
