だから私はRaspberry Pi 4をOpenWrtルーター（アクセスポイント、何と呼んでも）に設定する方法についての情報をインターネットから収集しました。 WiFiを動作させ、iPhoneから接続できるようになって嬉しいです。ああ。これまで私が思いついた内容は次のとおりです。https://docs.google.com/document/d/e/2PACX-1vQ2lDbAXV3b2Fzw9-LC7PRkirLQGqRH-iLm6cNcUz_b4lawJG_-57yWQKrYrbO8awSCcY_koax8os2e/pub（あいまいな形式で申し訳ありませんが、テスト中にこれを入力しました。） ACモードおよび/または80MHz帯域に入ることができないようです。私が去った後、"htmode": "VHT80"ネットワークが消えたようです。うまく動作しているようですVHT20。VHT40また、いくつかの異なるチャンネル+のVHT80組み合わせを試しましたが、役に立ちませんでした。
たぶん、誰かがこれについてもっと幸運になるでしょう。それとも、これはPiの現在のファームウェアの制限ですか？
2020年5月8日最新のスナップショットイメージ（）でテスト中ですopenwrt-bcm27xx-bcm2711-rpi-4-ext4-factory。
コメントありがとうございます！
