Well, the page I linked to in my other post says that the BCM4311 is
supported, so go have a look and see if it helps get you connected (
http://wireless.kernel.org/en/users/Drivers/b43 just so's you don't need
to go looking for the other post.

The good news is that apparently Broadcom has opened their software to
Linux developers and the drivers will be incorporated in future Linux
kernels.

Broadcom is the worst for open source drivers, but you can always use
Windows drivers if there isn't a Linux one by installing ndiswrapper. So the
good news is that you should be able to get any wireless working.

Type: lshw and scroll back to the section called *-network

Look at the bottom under configuration to see if it lists a driver or if it
says UNCLAIMED. If it lists a driver then you should be able to set up your
wireless using the wireless network tool in the system tray. If it says
UNCLAIMED then you need a driver. You can try Hardware Drivers in the
Administration menu or if there is none then install ndiswrapper and ndisgtk
using Synaptic, apt-get or software centre. The latter one is a GUI for
ndiswrapper that simplifies using the Windows driver. You will need your
driver disk for Windows.

OK. "lshw" revealed-

*-network DISABLED
description: Ethernet interface
physical id: 1
logical name: pan0
serial: 3e:c8:6e:26:f7:51
capabilities: ethernet physical
configuration: broadcast=yes driver=bridge driverversion=2.3 firmware=N/A
multicast=yes

The Ethernet network, on the other hand, is not labeled CLAIMED, UNCLAIMED, or
DISABLED

Gash, but I seem to be outfoxed at every turn!

Is there any reference to Broadcom at all? Try Hardware Drivers in
Administration next and if there are no proprietary drivers then you will
have to go the ndiswrapper route.

Oh, yeah, Broadcom is mentioned... it's a 4311 (blah, blah, boah) card.
