    电脑是惠普暗影精灵3，装了deepin15.6双系统，进入系统后有无线网卡但是搜不到任何网络：无线网卡是t8822be,
    我重新下载了一个无线网卡驱动，但是make的时候直接报错：


    qinoq@qinoqPC:~/Downloads/rtlwifi-next$ make
    make -C /lib/modules/4.15.0-21deepin-generic/build M=/home/qinoq/Downloads/rtlwifi-next modules

    原来15.5还可以自己安装无线网卡驱动，现在15.6make就报错，自带的又搜不到网络，谁能解决一下，这是 lspci-v的显示：

    试试安装新的驱动程序：

    sudo apt-get install git build-essential
    git clone https://github.com/rtlwifi-linux/rtlwifi-next.git
    cd rtlwifi-next
    make
    sudo make install
    echo "options rtl8822be ips=N" | sudo tee /etc/modprobe.d/rtl8822be.conf

    Makefile:976: "Cannot use CONFIG_STACK_VALIDATION=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel"

    • 复制 rtl8822befw.bin
           sudo cp rtlwifi-next/firmware/rtlwifi/rtl8822befw.bin /lib/firmware/rtlwifi/

    • 重新加载模块
          sudo modprobe -r r8822be
          sudo modprobe r8822be

    这里是有详细的

    https://bbs.deepin.org/post/167024#2楼主也可以看一下这个方法，我当时也是和楼主一样的情况，驱动即使重装了也没用，希望这能有所帮助
