最近、RT3572 チップベースの USB WiFi アダプターを購入しましたが、5Ghz ホットスポットを作成できないようです。Ubuntu 22.04 で作成しようとすると、dmesg の出力は次のようになります。
これが私のホットスポットの設定です (wlx0013eff709bd は Ubuntu が RT3572 アダプタに付けた名前です):
コマンドを使用するとiwAPモードを使用できることが確認されます
さらに、5Ghz 帯域でサポートされている周波数のリストは次のとおりです。
参考になれば幸いです。私の国コードはPKです
PS: このアダプタを raspAP を実行している Raspberry piOS に接続し、そこに 5Ghz ホットスポットを作成してみました。以下は hostapd のログ ファイルの出力です (ここでは、RT3572 は wlan1 です)。

答え1
5Ghz WiFi アクセス ポイントにアクセス ポイントがあり、ubuntu 20.04 と hostapd (Ubuntu サーバー バージョン - GUI なし) が実行されていました。
Ubuntu 22.04 にアップグレードした後、アクセス ポイントが機能しなくなりました。多くのページを読んだ後の結論は、規制の変更 (国によって異なります) により、ハードウェアでサポートされていない他の 802.11 標準が要求されるということです。
これはあなたが提供した最後のログで明確に確認できます:
Could not select hw_mode and channel. (-3)
wlan1: interface state COUNTRY_UPDATE->DISABLED
wlan1: AP-DISABLED
回答の検証:
22.04の代わりに20.00をインストールすると、APは5Ghzで動作します
オプション:
- 郡コードを偽装して、5Ghz APを許可する国を探します
- 他のハードウェアを入手します。
- 2.4GHzへ移行
