私のデスクトップはWindowsとUbuntu 22.04デュアルブートを使用します。以前もこの問題がありましたが、早く消えました。問題は、私のスペクトラムWi-Fiが同じデバイスのWindowsを含むすべてのデバイスに接続されていますが、Ubuntuには接続されていないことです。 1年以上働きましたが、何らかの理由で動作が停止しました。
この問題を診断する方法についていくつかのコメントを聞きたいです。それも奇妙な方法でつながっていますね。ネットワークサービスを再起動すると、しばらくインターネットに接続してから黒に変わります。 Wi-Fiも接続されていますが、どのウェブサイトにもアクセスできません。
これはinxi -Nの出力です：
