Hi Jackie,

Reviewing one of your previous outputs (wpa_out_p1) we see:

wlan0: Automatic auth_alg selection: 0x1
No supported operating classes IE to add
wlan0: Trying to associate with 70:d9:31:0e:2c:00 (SSID=3D'WHU-STU' freq=3D=
2432
MHz)
wlan0: Cancelling scan request
wlan0: State: SCANNING -> ASSOCIATING
Limit connection to BSSID 70:d9:31:0e:2c:00 freq=3D2432 MHz based on scan r=
esults
(bssid_set=3D0 wps=3D0)
wpa_driver_bsd_associate: ssid 'WHU-STU' wpa ie len 13 pairwise 1 group 1 k=
ey
mg
mt 4
                                         ^^^^^^^^^^^^^
Above is the problem. This is the same problem my buggy Netgear router
exhibited with an open guest network when the primary network was configured
for WPA-PSK.

wpa_driver_bsd_set_drop_unencrypted: enabled=3D0
bsd_set_opt_ie: set WPA+RSN ie (len 13)

Again, we see an IE of 13 bytes telling wpa_supplicant to use the WPA proto=
col
with RSN encryption.

wpa_driver_bsd_associate: set PRIVACY 1

And of course privacy is enabled. Same thing I saw with the buggy Netgear.

wlan0: Setting authentication timeout: 10 sec 0 usec

@adrian, do you have any thoughts about this? Could the university be hosti=
ng
another AP for faculty and staff off the same hardware?
