Hostapd SSIDは数秒後に消えます。

私はラズベリーパイゼロとWi-Fiカードを介して別のWi-Fi接続を共有するためにHostapdを使用しています。 Raspberry Piが起動したら、携帯電話でSSIDを表示し、SSIDに接続して数秒間使用することもできます。これでSSIDが消えます。

Hostapd の状態にエラーは表示されません。

修正する:

以前はUSBイーサネットを使用してこのRaspberry Piをセットアップしました。これで、新しいイメージを再インストールし、ワイヤレスAP機能に必要なものを設定しました。問題が引き続き発生します。この問題は引き続き発生するため、sudo apt update && sudo apt upgrade -y構成エラーではなくバグに近いです。

誰でもこれをデバッグする方法を知っていますか？
