[arch-general] b43: wireless issues

[Magnus Therning]

I'm having problems getting my wireless connection to work properly.

It's a broadcom card, using the b43 driver.  It connects fine on
login, but once I actually use the network I'm disconnected and all
attempts to re-connect fail.

I've found some reports of similar behaviour online, but none seem to
offer any good solutions to it :-(  So I'm trying my luck in here
instead.

One person mentioned that things started working much better if he
limited the network to 802.11b (not g), but I haven't seen any obvious
way of achieving this.  Any hints on what I can do to test that
myself?

$ lspci -vnn |grep 14e4
03:00.0 Network controller [0280]: Broadcom Corporation BCM4312
802.11b/g [14e4:4315] (rev 01)

I did extract some stuff from dmesg that might be of importance, but I
really couldn't tell:

b43 ssb0:0: firmware: requesting b43/ucode15.fw
