wpa_supplicantが「ioctl [SIOCSIWENCODEEXT]：引数が無効です」エラーで接続しない！

Ubuntu Server 12.04がデスクトップシステムにインストールされ（テキストモードではXウィンドウは使用できません）、有線イーサネットが接続されておらず、ワイヤレスネットワークのみが使用可能です。 TP-Link TL-WN723N USBワイヤレスアダプターを使用して、ワイヤレスネットワークに接続します。

最初は、iwconfigを使用して接続しようとしましたが、WPA2で保護されたネットワークへの接続に使用できないことがわかりました。最初に、iwconfigは以下を示します。

lo        no wireless extensions.

eth0      no wireless extensions.

およびSudo iwlist wlan0 scanningは以下を示します。

Sudo ifconfig wlan0 upを実行した後、Sudo iwlist wlan0 scanningは以下を表示します。

wpasupplicantをインストールして、WPA2で保護されたワイヤレスネットワークに接続しました。ただし、このパッケージの使用にはいくつかの問題があります。

この回答 の指示に従ってみました

wpa_passphrase 'MYESSID12345' 'MYPASSWORD$1234567' > CONFIG_FILE

上記のコマンドの後、CONFIG_FILE（/etc/wpa_supplicant/wpa_supplicant.conf）を編集したため、次の内容が含まれます。

network={
    ssid="MYESSID12345"
    scan_ssid=1
    key_mgmt=WPA-PSK
    psk="MYPASSWORD$1234567"
    proto=RSN WPA
    pairwise=CCMP TKIP
    group=CCMP TKIP
    #psk=1234567890abcdef1234567890abcdef1234567890abcedf1234567890abcdef
}

次に、wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -Dwext -ddを実行します。結果は、stderrで次のエラーになります。

ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument

最後のコマンドの後、wlan0はDOWNになり、Sudo iwconfig wlan0 upコマンドを使用して再度構成する必要があります。また、私はこれが問題を解決するかもしれないというコメントに基づいてnetwork-managerパッケージを削除しようとしましたが、成功しませんでした。

また、次のようにwpa_supplicant.conf1ファイルを編集しようとしました：

wpa_supplicant.confの＃1を試す

network={
    ssid="MYESSID12345"
    #psk="MYPASSWORD$1234567"
    psk=1234567890abcdef1234567890abcdef1234567890abcedf1234567890abcdef
}

wpa_supplicant.confの＃2を試す

network={
    ssid="MYESSID12345"
    scan_ssid=1
    key_mgmt=WPA-PSK
    #psk="MYPASSWORD$1234567"
    proto=RSN WPA
    pairwise=CCMP TKIP
    group=CCMP TKIP
    psk=1234567890abcdef1234567890abcdef1234567890abcedf1234567890abcdef
}

まず、ルーターがTKIPではなくWPA2-AESを使用するように設定されている場合、幸運が得られると思います。

第二に、短くて簡単なルートが完璧に機能する場合、長く複雑なルートを取っていると思います。まず、現在のwpa_supplicant.confファイルをバックアップすることをお勧めします。

Sudo mv /etc/wpa_supplicant/wpa_supplicant.conf  /etc/wpa_supplicant/wpa_supplicant.bak

次に、/ etc/network/interfacesを編集することをお勧めします。

auto lo
iface lo inet loopback

auto wlan0
iface wlan0 inet static
address 192.168.1.150
netmask 255.255.255.0
gateway 192.168.1.1
wpa-essid MYESSID12345
wpa-psk MYPASSWORD$1234567

もちろん、ここで詳細を置き換えてください。インターフェイスを再起動します。

Sudo ifdown wlan0 && Sudo ifup -v wlan0

テスト：

ping -c3 www.ubuntu.com

Pingの結果が得られたら、接続されています。
