(Get the code!)
This problem still persists in Ubuntu 12.04. It is probably related to the Linux kernel because it happens in a lot of other major distros.
I found a partial solution to my problem. I deactivated the B/G/N wireless mode of my router and enabled G mode only. Might work with N mode only, but I can't afford to do that because I have a device that relies on G mode.
The ath9k driver is broken and some people claim that disabling hardware encryption (how safe is that?) and power management of the wireless device will fix the problem.
As I have noticed, these changes might improve those that have an absolute poor performance or a not very fast Internet connection so they won't notice the lack of higher speeds. The problem must happen differently according to router settings so disabling the driver options might seem to be a fix to some.
In my opinion, the driver is broken, probably relying on undocumented reverse engineering, thus they are presenting problems when working with different routers and wireless modes.
