NetworkManagerは複製されたMACアドレスに接続できません。

NetworkManagerは複製されたMACアドレスに接続できません。

ローカルイーサネットに接続するには、特定のMACアドレスを偽装する必要があります。それで、「Clone MAC Address」フィールドに記入しましたnm-connection-editor。その後、nm-applet回転アイコンが数秒間表示され、不要な遅いWiFiネットワークに戻り、一般的な信号強度アイコンを表示します。その後、約20秒後に回転するアイコンが数秒間再び表示され(コンテキストメニューにイーサネットに再接続しようとしていることが表示されます)、最後にNMはWi-Fiに戻ります。など、無期限に(はい)。

システムログには、上記のプロセスの各繰り返しごとに次のメッセージが表示されます(簡潔にするために、日付、ホスト名、タイムスタンプ、およびPIDを削除しました)。

NetworkManagerが自分で正常に接続できるようにする方法についてのアイデアはありますか?
