Wi-Fiに接続しようとすると、「ローカルの選択により認証が中断されました（理由：3 = DEAUTH_LEAVING）」

私のPCにDebian 9stretch（GNOMEデスクトップ）64ビットをインストールしました。 atherosファームウェアをインストールした後、USBワイヤレスアダプタ（TP-LINK TL-WN722N）が自動的に検出されました。

apt-get install firmware-atheros

ただし、パスワードで保護されているかどうかに関係なく、どの無線フレームにも接続できません。

USBを接続しました。検出され、認証を送信し、認証を受けますが、すぐに認証を中止します。 IPV6を無効にしても問題は解決しませんでした。これは私のdmesgレポートです：

なぜこれが起こるのか、一度の試みが何度も中断される理由がわかりません。
