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）。
