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.
