[arch-general] Broadcom B43 problems

[Krzysztof Warzecha]

There are few steps with can help you trobleshoot this:

1. try to connect with plain wpa_supplicant. Kill networkmanager,
wpa_supplicant and dhcpcd and everything else; create configuration
file:

network={
        ssid="$WIRELESS_SSID"
        psk="$WIRELESS_PASSPHRASE"
}

Save it as "wpa_supplicant.conf", start wpa_supplicant:
"wpa_supplicant -iwlan0 -c/home/magnus/wpa_supplicant.conf", try to
fetch configuration from dhcp: "dhcpcd wlan0". This way nm won't mess
with wifi chipset.

2. you can also load b43 module with "verbose=3 hwtkip=0 nohwcrypt=1"
or other options (check "modinfo b43").

3. maybe latest kernel just have issues with this chip, try linux-lts.
