Ubuntu 16.04 wifi Intel 7265低速/切断
ちょっと私はIntel 7265 wifiカードを備えた新しいAsus Zenbookを持っています、そして、数分で絶えずインターネット接続は非常に遅くなっています/まったく動作していません。 Intelサイトlwifiから最新のドライバーを入手しました。誰かが間違っていることを知っていますか？ dmesgからのメッセージは次のとおりです。

私は2台のIntelワイヤレスデバイスを所有して使用しています。私は数年でいくつかのテクニックと何千ものフォーラム投稿を磨きました。
まず、ルーターの設定を確認します。 WPA2-AESが推奨されます。 WPAおよびWPA2混合モードではなく、TKIPでもありません。 2番目に、ルーターがN速度に対応している場合、自動20/40 MHzではなく2.4 GHz帯域で20 MHzのチャネル幅を使用すると接続性が向上する場合がありますが、N速度に影響する可能性があります。また、自動チャネル選択ではなく、1、6、または11のいずれかの固定チャネルを使用する方が幸運です。また、ルーターがN速度のみを使用するように設定されていないことを確認してください。 auto B、G、およびNが優先されます。これらの変更を行った後、ルーターを再起動します。
次に、規制区域を明示的に設定することをお勧めします。あなたのものを確認してください：
Sudo iw reg get
00を取得した場合、それは1サイズ多分すべてに適した設定です。ここであなたを見つけてください： http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 それから一時的に設定してください：
Sudo iw reg set IS
もちろん、アイスランドでない場合は国コードに置き換えてください。永続的に設定します：
gksudo gedit /etc/default/crda
テキストエディタgeditがない場合は、nano、kate、leafpadを使用します。
最後の行を次のように変更します。
REGDOMAIN=IS
注意深く校正し、テキストエディターを保存して閉じます。
次に、Network ManagerでIPv6を無視に設定します。 http://docs.fedoraproject.org/en-US/...pv6-ignore.png この例はイーサネット用ですが、ワイヤレスが必要です。
最後に、ファームウェアを更新することをお勧めします。
cd /lib/firmware
Sudo wget https://github.com/OpenELEC/iwlwifi-firmware/raw/master/firmware/iwlwifi-7265D-21.ucode
再起動して、どのように機能するかを教えてください。
