authentication issues - understanding reason numbers

[Philipp]

Hi,
I try to use wpa_supplicant but have trouble getting a connection.
I tried multiple frontends, wicd, wifi-radar, netcfg, but to no avail,
and now I try since some time to use wpa_supplicant directly in order to
figure out what's wrong.
I'm trying at two different networks, a home router with WPA-PSK and my
university network (eduroam) with WPA-EAP (well, it's with
identity/password for each user but without cert).

I guess the home example should be simpler, so I'll start with that.
I tried the simple home network example and the catch-all example from
the config manpage: http://linux.die.net/man/5/wpa_supplicant.conf
Both configurations lead to the same output, here with the nl80211 and
wext driver respectively:

$ sudo wpa_supplicant -Dnl80211 -c/etc/wpa_supplicant.conf -iwlan0
Trying to authenticate with 00:1f:33:b6:24:42 (SSID='effe' freq=2437
MHz)
Trying to associate with 00:1f:33:b6:24:42 (SSID='effe' freq=2437 MHz)
Associated with 00:1f:33:b6:24:42
CTRL-EVENT-DISCONNECTED bssid=00:1f:33:b6:24:42 reason=15

$ sudo wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf                                                                            
Trying to associate with 00:1f:33:b6:24:42 (SSID='effe' freq=2437 MHz)
Associated with 00:1f:33:b6:24:42
CTRL-EVENT-DISCONNECTED bssid=00:1f:33:b6:24:42 reason=0

I couldn't figure out what the magic numbers reason=15 and reason=0
mean, and the -d or -dd output didn't tell me what's wrong either. I'm
pretty much out of ideas at this point.

Here's some information about my system:
Arch Linux, kernel 2.6.35.7
wpa_supplicant 0.7.3
BCM4312 14e4:4315
b43-firmware-4.178.10.4 (4.174.64.19)
b43-fwcutter 013


I'd really appreciate any help.

Best regards,
Philipp
