wpa_supplicantは、構成ファイルにessidおよび他のパラメーターを設定できません。

wpa_supplicantを使用してワイヤレスインターフェースでessidやその他のパラメーターを設定することはできません。

-Dwextを使って投げるioctl[SIOCSIWENCODEEXT]

 $ sudo wpa_supplicant -B -i wlan0 -Dwext -c universitywpa 
Successfully initialized wpa_supplicant
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument

また、ESSIDを設定できません。

 $ 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

以下を使用すると、-Dnl80211IOCTLエラーは発生しません。

$ sudo wpa_supplicant -B -i wlan0 -Dnl80211 -c universitywpa 
Successfully initialized wpa_supplicant

ただし、ESSIDはまだオフになっています。

$ 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

何が起こっているのかを確認するために、-d（verbose）と同じコマンドを実行しました。

しかし、これをどのように解釈するのかわかりません。

ESSIDが設定されていないのはなぜですか？

iwconfigを手動で実行すると、ESSIDを設定できます。

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

 $ 

しかし、明らかに接続が機能するには、ESSID以上が必要です。

大学WPAの内容：

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"
}

私はこの設定を使って問題なく他のコンピュータに接続しました。しかし、私はいつも-Dnl80211を使わずに-Dwextを使います。

運転手はですiwlwifi。

これはiwlwifiと-Dnl80211の間の問題ですか？この問題をさらに診断するにはどうすればよいですか？
