Yes, the bcm43xx driver is ugly.  Finally got it to work last night by
placing the AP in WEP Open Authentication. The driver won't work with
WEP Shared Key, or WPA/WPA2 in any mode.  And, there is a lot of packet
loss. This won't do for a laptop that has to go back to college and hit
a lot of APs that may be configured with WPA.

Next step is to remove the bcm43xx driver and replace it with the more
modern b43 driver from Broadcom.

Here is some more info I captured last night:
