最近の月の間に問題なくArch Linuxを使用した後、ワイヤレスip linkインターフェイスは表示されませんでした（以前はwlp2s0）。私はすべてを再起動しました。魔法的な修正はありません。だからインストールメディアから起動しました。ip linkインストールメディア（wlan0）にワイヤレスインターフェイスが一覧表示されており、ネットワークに接続してもwifi-menuエラーは発生しません。ただし、google.comをpingしても応答し続けますtemporary failure in name resolution。
今奇妙な部分があります。 chrootingを使用せずにメディアから（メディア以降）マイarch-chrootコンピュータに入ると、インターネットに正しく接続できます。wifi-menuwifi-menu
以下はいくつかのコマンドの出力です。
