This is probably a long shot, but...
I had problems a couple years back with the ralink driver on Ubuntu.
Running /sbin/iwconfig showed that the Rate was always something very
close to 1 (bottom of the scale, I forget the units). Connections were
horribly slow.
I could run "/sbin/iwconfig wlan0 rate 54M" and it would fix things
until next boot.
