I am using the b43 driver on ubuntu 13.10 to run my BCM4306 (rev 3). I got it running using the instructions here.
My issue is that when I am using the wireless on this computer, often the performance is poor - downloads restricted to 34kpbs where realistically they could be as high as 1,300. Beyond this, other devices suffer internet slowdowns when this computer is connected - Confirmed through shutting the computer off.

Is there anything I can do (beyond replacing this card)?
