wpa_supplicantを使用してWi-Fiホットスポットに接続できないのはなぜですか?

モバイルサービスを使用しているAndroid携帯電話で「Wi-Fiホットスポット」をオンにしましたが、コンピュータがWi-Fiに接続できないのはなぜですか?ありがとうございます。

答え1

nl80211: kernel reports: Match already configured

これは、ワイヤレスインターフェイスを制御するために競合する複数のネットワーク構成サブシステムがある可能性があることを示しています。アーチフォーラムの議論のように

wpa_supplicantスタンドアロンモードで使用する予定の場合、NetworkManagerやnetctlなどの他のものも同じインターフェイスを管理することはできません。またはを使用している場合は、他のプロセスを開始する前に、以前の試行の以前のプロセスが実際に終了していることをwpa_supplicant確認してください。wpa_supplicant

DHCPクライアントを使用している場合dhcpcd(Raspberry Pi OSがデフォルトで使用している場合)、ネットワークdhcpcdインターフェイスを自動的に検出し、wpa_supplicantワイヤレスインターフェイスを自動的に起動するように設定できます。

nl80211: Could not set interface 'p2p-dev-wlp5s0' UP
nl80211: deinit ifname=p2p-dev-wlp5s0 disabled_11b_rates=0
p2p-dev-wlp5s0: Failed to initialize driver interface
P2P: Failed to enable P2P Device interface

何らかの理由で、システムは2つのWiFiクライアントがホットスポット/アクセスポイントなしで互いに直接通信するp2pモードでインターフェイスを設定しようとします。

wlp5s0: SME: Trying to authenticate with xx:xx:xx:xx:xx:xx (SSID='moto g pure' freq=2437 MHz)
wlp5s0: Trying to associate with xx:xx:xx:xx:xx:xx (SSID='moto g pure' freq=2437 MHz)
wlp5s0: Associated with xx:xx:xx:xx:xx:xx
wlp5s0: CTRL-EVENT-SUBNET-STATUS-UPDATE status=0
wlp5s0: WPA: Key negotiation completed with xx:xx:xx:xx:xx:xx [PTK=CCMP GTK=CCMP]
wlp5s0: CTRL-EVENT-CONNECTED - Connection to xx:xx:xx:xx:xx:xx completed [id=0 id_str=]

これは、認証された接続が正常に確立されたことを示します。

wlp5s0: CTRL-EVENT-DISCONNECTED bssid=xx:xx:xx:xx:xx:xx reason=1 locally_generated=1
wlp5s0: No network configuration found for the current AP

...しかし、コンピュータは接続をどのように行うべきかわからないので、自動的に切断することを決定します(接続切断がローカルで作成されたと表示されます)。静的IPアドレスを設定する必要がありますか、DHCPを試す必要がありますか、それともIPv6専用接続である必要がありますか?

ネットワークSSIDとWPAパスワードを定義するwpa_passphrase "moto g pure" "mypassword"最小フラグメントを作成します。wpa_supplicant.confただし、出力をパイプする試みは、対応するオプションが必要なため機能しない可能性がありwpa_supplicant -cます-c構成ファイルのパス名

Arch wikiが提案するコマンド形式は多少異なります。既存および/またはプロセスを停止しwpa_supplicantたら、次dhcpcdを実行してみてください。NetworkManagernetctl

sudo wpa_supplicant -D nl80211,wext -i wlp5s0 -c <(wpa_passphrase "moto g pure" "mypassword")

この構文は、含まれているコマンドの出力に基づいて一時ファイルを生成し、<( ... )基本コマンドを実行する前にコマンドラインの構成を一時ファイル名に置き換えます。<( ... )
