Wi-Fiに接続できない、iwconfigにwlan0デバイスがない
Lenovo Ideapad 500S-14ISKを購入してDebian 8をインストールしました。これは新規インストールであり、このコンピューターには他のOSがありません。
Wi-Fiへの接続に問題があり、ヒントを探すために何日もグーグルで検索した結果、何の効果もありませんでした。

必要なファームウェアとバックポートをインストールすると、Wi-Fiが有効になります。
これらのコマンドは、Lenovo Ideapad 500S-14ISKのDebian 8で問題なく動作します。
いくつかの基本的なツールをまだインストールしていない場合は、最初にインストールします。
Sudo apt-get install vim git build-essential
ファームウェアを入手 githubから、必要なファイルをシステムフォルダーにコピーします。
# assuming that you use your Downloads folder to store the files needed.
cd ~/Downloads
git clone https://github.com/kvalo/ath10k-firmware.git
cd ath10k-firmware/QCA9377/hw1.0
Sudo mkdir -p /lib/firmware/ath10k/QCA9377/hw1.0
Sudo cp board.bin /lib/firmware/ath10k/QCA9377/hw1.0
Sudo cp firmware-5.bin_WLAN.TF.1.0-00267-1 /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin
Sudo modprobe -r ath10k_pci
（私は実際には最後の行で何も変更されないと思いますが、私は何も台無しにしないように確かにそうしていました）
バックポートをダウンロード、ビルドしてインストールし、再起動します。
cd .. # getting back to the Downloads folder
wget https://www.kernel.org/pub/linux/kernel/projects/backports/2015/11/20/backports-20151120.tar.gz
tar -xf backports-20151120.tar.gz
cd backports-20151120
make defconfig-ath10k # pray for the make process here goes flawlessly.
make
Sudo make install
Sudo modprobe ath10k_pci
Sudo reboot
（ath10k_pciは再起動後に実行を開始するため、再起動前の最後の行は不要でしたか？）
