[Rack] Cisco APs

Jake and I tried to get one of the 1220 Aironet bridges to replace the
flaky wireless interface on MC hawking, the wheelchair robot.

After trying the obvious and not passing frames across the link, I
found out the 1220 series can't bridge to anything besides another
Aironet device.  A feature called "universal workgroup bridge" allows
this, but doesn't seem to be available in any build for the 1220

Bridging to the 1100 series APs doesn't work because they have G
radios and the 1220 series only have B radios.  I don't know why they
won't agree to use the 11 megabit modulation they have in common, but
there's something in the firmware that won't allow it:

   %DOT11-4-CANT_ASSOC: Interface Dot11Radio0, cannot associate: No
matching rates

We have other 1220 bridges, but no power supplies.  Does anyone have a
48V DC supply to get another 1220 bridge online?
