暗影精靈3安裝無線網卡驅動(ubuntu16.04)

干貨，無線網卡安裝步驟：

1. 由於暗影精靈3的無線網卡較新，版本為Realtek Device b822,(查看命令為lspci | grep -i net，Ethernet controller代表有線網卡、Network controller為無線網卡標志);

    linux內核中沒有兼容的網卡驅動，所以需要手動安裝適配無線網卡的驅動程序，命令如下

    sudo apt-get install git build-essential
    git clone https://github.com/rtlwifi-linux/rtlwifi-next.git
    cd rtlwifi-next
    make
    sudo make install

2. ！！！但是上述命令編譯成功的前提條件是linux內核為4.8版本，如果不是有可能編譯出錯。下面介紹升級內核的方法：

 

    cd /tmp  
    sudo mkdir mydebs  
    cd /tmp/mydebs

    wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8/linux-headers-4.8.0-040800_4.8.0-040800.201610022031_all.deb  
    wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8/linux-headers-4.8.0-040800-generic_4.8.0-040800.201610022031_amd64.deb  
    wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8/linux-image-4.8.0-040800-generic_4.8.0-040800.201610022031_amd64.deb

    wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8/linux-headers-4.8.0-040800_4.8.0-040800.201610022031_all.deb  
    wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8/linux-headers-4.8.0-040800-generic_4.8.0-040800.201610022031_i386.deb  
    wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8/linux-image-4.8.0-040800-generic_4.8.0-040800.201610022031_i386.deb  

 下載完成后, 使用dpkg命令安裝所有的.deb包

    sudo dpkg -i *.deb  

 至此內核升級成功！

 然后重新編譯步驟1里的驅動程序，安裝成功后重啟電腦，就可以成功連上wifi啦！！！
