これは私の最初の投稿なので、投稿場所、フォーマット、その他に関して修正すべき点があれば教えてください。
簡単に言うと、 で説明したように、私の WiFi カード (Intel Centrino Wireless-N 2200)lshw -class netowkrが動作しなくなり、正直に言って修復方法がわかりません。この問題のトラブルシューティングに役立つ可能性があるいくつかのコマンドの出力を提供しましたので、他に必要な情報があればお知らせください。
これは Thinkpad x230 で発生しており、Fn + F5 を押して Wi-Fi を切り替えても機能しません。Fedora で機内モードをオンにすると、Wi-Fi 機能が壊れる可能性がある一般的なバグであるという記述を見ました。
私が試したこと:
-sudo rfkill unblock all
再起動
- カーネル 5.5.6 から 5.5.7 および 5.5.8 へのアップグレード。この問題はすべてのカーネル バージョンで発生しています
- sudo rmmod iwldvm、続いてsudo modprobe iwldvm。この後、rfkill はハード ブロックされていないことを示しますが、Wi-Fi を有効にする試みはすべて失敗します
- GUI を使用して Wi-Fi を有効にする -
BIOS で WLAN を無効にしてから再度有効にする
- BIOS でワイヤレス関連のすべての設定を有効にする。Wi-Fi の動作は、Bluetooth と WWAN が有効になっているかどうかとは関係ないようです
- 続いてこのリンク関連するドライバをインストールし、cp iwlwifi-2000-6.ucode /lib/firmwareドライバに添付されているREADMEに記載されている通りに実行しました。
システム設定に記載されている仕様は次のとおりです

答え1
ワイヤレスハードウェアスイッチはずっと有効になっていたが、数回オンとオフを切り替えると問題は解決した。
