Public bug reported:
Hi, I use Tenda w522u dual band wireless adapter (RT3572) and although
it CAN see networks and CAN connect to them, the bandwith is really
terrible. The internet is very slow although with another wireless
adapter it is much better (600Kbits/sec versus 15Mbit/sec aproximately)
It seems the driver is somehow bad.
I did not install the proprietary version of driver (I do not want to
compile every time I upgrade kernel)
