Gavin, Are you getting the speed from the NetworkManager applet, because that only reports on the initial connection speed of the interface. To get a current rate you must use iwconfig or another application that gets the rate dynamically. The code for the b43 driver starts the interface at a low rate and constantly monitors the signal quality and adjusts the transmission power and rate depending on the quality. In a good environment the connection should remain reliable and the driver will steadily increase the transmission rate. The less reliable the connection the lower the rate. I consistently get 12-24 Mb/s with the driver on a stock Fedora 7/8 kernel on a 4318. I have had connection quality problems before, related to the channel I was using and interference from various other AP's in the neighbourhood. So you might want to check this. Thanks Simon.
