TP-Link WN822NのWifi問題（Ubuntu 13.10）
Ubuntu 13.10でWi-Fiに少し問題があります。 UbuntuやLinuxを使用したことがありません。新しいPCにインストールしたばかりで、TP-Link WN822N USBワイヤレスネットワークアダプターを使用してインターネットを実行しています。問題は、インターネットが保持し続けることです。つまり、接続はそこにあり、一見機能しているように見えますが、約5分後には何もしなくなります（実際にドロップアウトすることはありません）。切断してから再接続すると、さらに5分間動作し、すすいで繰り返します。
誰が私がこれを修正できるかについてのアイデアを持っていますか？

同じ問題がありました。 RTLドライバーはそれほど良くないので、ありがたいことに、かなり賢い人たちが良い解決策を見つけました。私はちょうどそれをインストールし、紛失したり、ドロップアウトすることなくしっかりと接続しています。これらのリンクをたどり、注意深く読んで適用してください：「最初に理解してください」 （-スザンヌブラウン）。笑顔があなたを待っています。
https://github.com/pvaret/rtl8192cu-fixes/blob/master/README.md （フォローするのは最も簡単ですが、あなたが何をしているかを理解するために他の人を読んでください。）
これは回答ではありませんが、重要な情報のトラブルシューティングに役立ち、メッセージが長すぎてコメントに入れることができません。ごめんなさい。
自動バージョン：（スクリプトを使用）
ワイヤレス接続のトラブルシューティングを支援するために、簡単なスクリプトを実行していくつかの重要な情報を追加できます。
- これをダウンロード： wificheck.sh
- HOMEフォルダーにファイルを配置します（
~/または/home/username） - ターミナルを開きます（CTRL-ALT-T）
スクリプトを実行します（質問はフランス語ですが、はいの場合は 'y'と答えます）：
Sudo bash wificheck.sh && Sudo chmod 777 wificheck.log新しく作成されたファイルwificheck.logを開き、Askubuntu.comまたはUbuntuforums.orgにコンテンツを投稿します
ハードウェア/ソフトウェアのwifi関連に関するすべての情報が含まれています。
マニュアルバージョン：（コマンドライン、コピー＆ペースト、テキストエディターを使用）
これで、これはスクリプトと同じことを行います（=ワイヤレス接続のトラブルシューティングに役立つ情報を提供します）が、スクリプトはありません。コマンドラインを使用してすべてを手動で行います。各コマンドの戻り値をテキストファイルまたは開いたスレッドに貼り付けます。
