Ubuntu 14.04での不安定なワイヤレス接続
最近、14.04にアップグレードしました。Wi-Fiネットワークに接続してから一定の時間が経過すると、コンピューターが突然切断され、Wi-Fiを無効にしてから再度有効にする必要があります。これは、特にファイルをダウンロードするときの私にとって大きな問題です。修正はありますか？他の修正に加えていくつかの投稿が示唆するように、私はすでにIPv6を無効にしようとしました。助けてください、私のコンピューターは64ビットで動作します。
スクリプトを実行した結果は次のとおりです。

このドライバーには問題がありますが、通常よりうまく機能させるためにできることがいくつかあります。
まずルーターの変更802.11bgnから802.11bg。
次に、wpa/wpa2暗号化をwpa2（CCMP）（AES）ではなく（TKIP）に変更します（オプションがある場合）。
3番目に、ルーターのワイヤレスチャネルを1または11に設定し、ルーターの構成を保存して再起動します。
4番目は、画面の右上隅にあるネットワークマネージャーに移動し、[接続の編集]> [ワイヤレス]タブをクリックし、IPV6を無視するように設定します。
5番目のターミナルCTRL + ALT + _Tを開き、次のコードを1行ずつコピーして貼り付けて正確にします。
echo "options rtl8192ce swenc=1 ips=0" | Sudo tee /etc/modprobe.d/rtl8192ce.conf
Sudo modprobe -rfv rtl8192ce
Sudo modprobe -v rtl8192ce
