レノボY520レギオンでのWIFIドロップの問題

LENOVO legion/Ideapad Y520に問題があります...

ラップトップを購入し、64ビットUbuntu最新バージョン17をインストールしました。

ハードブロックを削除してWi-Fiを有効にしましたが、その後もWi-Fiが接続されてしばらく動作しますが、その後ドロップ、切断されます。ログにはwpa_supplicantパッケージに関するいくつかの問題が示されていますが、修正できませんでした。

UbuntuとKali Linux v2（2017）を再インストールしようとしました。同じ問題がありました。

何が起こっているのか分かりません。ドライバーを再インストールしようとしましたが、成功しませんでした。

/var/log/syslogからのログファイルの私の部分は次のとおりです。

私は現在Ubuntu 16.04.3を使用しています、要求されたコマンドの出力は次のとおりです：

user@home:~$ Sudo lspci -knn | grep Net -A3

上記で送信したエラーはUbuntuの場合と同じですが、必要に応じてUbuntu syslogも配置します。 （ ここから前から 再起動network-managerおよび 後から と読むことができます。）

deepsec

2日間の戦いの後、私は修正を見つけたように見えます。

Ubuntu 16.04/17でy520 Legion/Ideapad lenovoラップトップで同様の問題が発生する場合は、次を試してください。

最初にすべきことは

必要なドライブを正確に調べる：

deepsec@deepnetwork:/tools$ Sudo lspci -knn | grep Net -A3 
03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. 
RTL8821AE 802.11ac PCIe Wireless Network Adapter [10ec:8821] 
Subsystem: Lenovo RTL8821AE 802.11ac PCIe Wireless Network Adapter 
[17aa:a814] Kernel driver in use: rtl8821ae Kernel modules: rtl8821ae 
04:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. 
RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 10)

だから私にとっては

RTL8821AE

次に、次のコマンドを使用して、githubからこのドライバーをインストールしました。

deepsec@deepnetwork:/tools$ cd /tmp
deepsec@deepnetwork:/tmp$ Sudo apt-get install build-essential linux-headers-generic git dkms
deepsec@deepnetwork:/tmp$ git clone http://github.com/lwfinger/rtlwifi_new.git
deepsec@deepnetwork:/tmp$ cd /tmp/rtlwifi_new
deepsec@deepnetwork:/tmp$ make
deepsec@deepnetwork:/tmp$ Sudo modprobe -rv rtl8821ae
deepsec@deepnetwork:/tmp$ Sudo make install
deepsec@deepnetwork:/tmp$ Sudo modprobe -v rtl8821ae

上記の解決策は、1つのエラー修正で私を助けた後、次のコマンドを使用してnetwork-managerとpptp gnomeを削除し、wicd（network-managerの代替）をインストールする必要がありました：

Wicdのインストール、network-managerの代替：

deepsec@deepnetwork:/tools$ Sudo apt-get install wicd 
deepsec@deepnetwork:/tools$ Sudo apt-get install wicd-gtk

次に、network-managerのような上部のアイコンにwicdを追加する必要があります（デフォルトでは、このオプションはありません）。

Ubuntu 16.04+以上のソリューション：

deepsec@deepnetwork:/tools$ Sudo apt-get install python-appindicator

16.04ソリューション以下のすべてのバージョン：

https://askubuntu.com/questions/69005/wicd-tray-icon-doesnt-show

リブートして、右上のcorrnetにwicdのアイコンがあることを確認し、wicdも機能しているかどうかを確認し、利用可能なすべてのwifi接続をスキャンできるようにします。

すべて問題なければ、network-managerを削除します。

deepsec@deepnetwork:/tools$ Sudo apt-get purge network-manager
deepsec@deepnetwork:/tools$ Sudo apt-get purge network-manager-pptp-gnome
deepsec@deepnetwork:/tools$ Sudo apt-get purge network-manager-pptp

私は私の接続ディイントが48時間以上落ちたのに気づいたので、私はその罰金を推測します、私が上に投稿したエラーはもうありません。
