My card (a 4306) seems to be running at 11Mbps.  No idea how to change
it: iwconfig doesn't report the current rate (I had to go digging in
sysfs) and trying to change it with iwconfig fails with "Operation not
supported".

Here's the signal info:

        Link Quality=228/100  Signal level=-32 dBm  Noise level=-70 dBm

The machine is about 3 metres from the AP.
