5GHzを使用するワイヤレス機能が失われました（PCE-AC68）
PCE-AC68デュアルバンドワイヤレスAC1900 PCI-Eアダプター、Ubuntu 15.10が完全に更新されました。
昨年のどこかでこれを購入し、いくつかのオンラインリソースをインストールして使用し、802.11acの全速度を有効にすることができました（手順は覚えていませんが、複雑ではありませんでした）。
5GHzと2.4GHzの両方を備えたルーターに接続しています。
数か月間はうまく機能しましたが、しばらく前から5GHzはリストに表示されず、SSIDを手動で指定しても追加できませんでした。電話とタブレットは以前と同じように5GHzを使用し続けるので、まだそこにあります。
私が考えることができるすべての再起動などを試行しました。
Wireless.txtスクリプトを実行しました。その結果、5GHzチャネルと詳細情報を確認できましたが、結果を実際に解釈することはできませんでした。
これが何であるかについての考え/私の設定を見て助けてください。 :)

私はあなたと同じ問題を抱えていた、そして私は問題を見つけた。 5Ghzネットワークは自動的にチャネルを選択するように設定されていましたが、ある日、それが大きな番号のチャネルに変更され、カードがネットワークを見つけることができなくなりました。
そのため、ネットワークに多数のチャネルがあるかどうかをルーターにチェックインし、それを低いチャネルに戻し（現在はチャネル40で正常に機能しています）、再びネットワークを見つけることができるかどうかを確認します。
また、bcmwlパッケージページでバグレポートを開きました。これが問題である場合は、 このページ の[このバグがあなたに影響を与える]ボタンをクリックします。
お役に立てば幸いです。
