さらに驚くべきことは、lshwとlspciの両方が有線イーサネットコントローラ/アダプタに関連するものを表示しないことです。 lshw：

私のラップトップの有線イーサネットが表示されないのはなぜですか？どのようにデバッグできますか？
Debianのインストールはもともとこのシステムにあったものではありません。マザーボードが壊れた古いラップトップにあったので、Debianのインストールと一緒にハードドライブも回収しました。しかし、私はこれが有線ethコントローラを検出できないlspciに関連していると思います。
答え1
BIOSで有線ネットワークカードが無効になっていないことを確認してください。
