That does seem a bit odd; if there's trouble down the line, I suppose
you could try purging both the cutters and then reinstalling
b43-fwcutter, but it seems from the subsequent output that we won't
need to.

I don't understand it fully myself, but the way to think of it is that
each hardware device that's supported by the mac80211 kernel code that
underlies many modern drivers gets a wmaster interface created for it,
and then the individual drivers can create one or more normal, usable
network interfaces. [There can indeed be more than one; you can have
wlan0 in managed (client) mode, and mon0 in promiscuous, scanning
monitor mode, both based off a single wmaster0 "interface".] On my
system, I have an internal Broadcom card, as well as a PCMCIA Atheros
card that I sometimes use. When they are both plugged in, I'll have
wmaster0 for the Broadcom and wmaster1 for the Atheros, and eth0 for
the normal Broadcom client mode interface (renamed from wlan0 by udev),
perhaps mon0 for the Broadcom in monitor mode, ath0 for the Atheros in
client mode, etc.

At least somewhat working :).

From
http://www.wirelessroomservice.com/2wire-homeportal-1000-series-adsl-broadband-wireless-access-gateways
Default SSID on 2Wire Routers: 2WIRExxx (where xxx is the last three
digits of the products serial number that can be found on the bottom of
the your 2Wire HomePortal.
So someone's probably running a 2Wire router near you, and has left it
on its default settings. Bad idea.

Sorry, the iwconfig command should be:
iwconfig wlan0 essid your-essid mode managed

The key question here is whether 'iwconfig wlan0' will show that you
are now associated. If the second line contains 'Access Point:
xx:xx:xx:xx:xx:xx:', you're good. If it says 'Not-associated', not so
good ...
What IP range does your AP use? If it's on a different subnet from
your eth0, then pinging it should tell you whether you're connected
properly, and I suppose that you could always do 'ping xxxxxxxx -I
wlan0' to ensure that you're using the right interface, although I
don't have any experience with that option. BTW, when I suggested that
you give the card an arbitrary IP address, I think that that will only
work if you use the proper IP scheme relative to your AP's. The
documentation of the AP should tell you what IP address and subnet it's
using. Most SOHO APs do DHCP out of the box, so if the connection to
the AP is okay, then running 'dhclient wlan0' should get you an IP
address from the router.

This looks okay, but you seem not to have b43 debugging on (it's an
option in the kernel, in the b43 driver section). The devs often gripe
about distros that don't enable it on their stock kernels, thereby
causing people to bug them with insufficient debug information. I use
custom kernels, hewing pretty closely to the Kent West 10 step
procedure :)
