Não consigo usar o wpa_supplicant para definir o essid e outros parâmetros na interface sem fio.
Usando -Dwext lança ioctl[SIOCSIWENCODEEXT]
$ sudo wpa_supplicant -B -i wlan0 -Dwext -c universitywpa
Successfully initialized wpa_supplicant
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument
e também não define o ESSID:
$ iwconfig wlan0
wlan0 IEEE 802.11abgn ESSID:off/any
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=15 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Power Management:off
Se eu usar -Dnl80211
, nenhum erro IOCTL será lançado:
$ sudo wpa_supplicant -B -i wlan0 -Dnl80211 -c universitywpa
Successfully initialized wpa_supplicant
Mas o ESSID ainda está desativado:
$ iwconfig wlan0
wlan0 IEEE 802.11abgn ESSID:off/any
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=15 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Power Management:off
Eu corro o mesmo comando com -d (verbose) para ver o que pode estar acontecendo:
$ sudo wpa_supplicant -B -i wlan0 -Dnl80211 -c universitywpa -d

Mas não sei como interpretar isso.
Por que o ESSID não está sendo definido?
Se eu executar o iwconfig manualmente, posso definir o ESSID:
sudo iwconfig wlan0 essid UNIVERSITY-SECURE
$ iwconfig wlan0
wlan0 IEEE 802.11abgn ESSID:"UNIVERSITY-SECURE"
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=15 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Power Management:off
$
Mas, obviamente, há mais do que o ESSID necessário para fazer a conexão funcionar.
conteúdo do universitywpa:
network={
ssid="UNIVERSITY-SECURE"
scan_ssid=1
key_mgmt=WPA-EAP
pairwise=CCMP TKIP
group=CCMP TKIP
eap=PEAP
identity="my-user"
password="mypass"
ca_cert="university_comodo_cert.pem"
phase1="peapver=0"
phase2="MSCHAPV2"
}
Eu usei essas configurações para conectar em outras máquinas sem problemas. Mas eu sempre usei -Dwext, nunca -Dnl80211.

.
Este é um problema entre iwlwifi e -Dnl80211? Como faço para diagnosticar ainda mais esse problema?
