[Bug 665364] [NEW] RT2561 (rt61pci) connectivity close to unusable again

[mnemoc]

Public bug reported:

this problem comes and goes since 9.04, bit rate goes from 54MB/s to
1MB/s very dinamically... even at 1 meter of the AP. It was quite decent
in 10.04 but I upgraded to 10.10 and it's close to unusable again. `sudo
iwconfig wlan0 rate 54M` solves the problem during a few minutes only.
linux-backports-modules-wireless-maverick-generic didn't help either.
