I have a similar issue here, RTL8191SEvA and 12.04.1 (3.2.0-35-generic) also on a low power machine (Atom D510).

The issue manifests itself periodically, but it does seem only when there is moderate network load (MythTV video streaming). It's quite frequent (we can't get through a half hour show without issues).

Interestingly, I first thought it was my WiFi system (Unifi) as I purchased both at the same time and it also seems to cause the AP to struggle for other connected clients as well. I'm now suspecting it is the linux driver with this chipset after finding this bug.

Here is a thread I started on the Unifi forums:

Note that behavior sometimes will go back to normal after 30sec or so, and sometimes can only be resolved with a reboot.
