    问题描述

    按这篇文章的操作来的: 下载 Github 上的驱动,下载完.zip 文件后,进行如下步骤:

    unzip rtl8188eu-master.zip
    cd rtl8188eu-master
    sudo make
    sudo make install
    sudo modprobe 8188eu
    

    重启电脑后,发现找不到无线网卡

    lucy@lucy-computer:~$ iwconfig 
    enp4s0    no wireless extensions.
    
    lo        no wireless extensions.
    

    lsusb 命令是能够看到设备的

    你这个很奇怪啊,怎么默认会让 mediatek 的驱动来处理这块网卡呢…

    你把 mt7601u 暂时禁用试试:
    sudo echo 'blacklist mt7601u' >> /etc/modprobe.d/blacklist-mt7601u.conf

    然后重新插拔一下看看 dmesg 里有没有 8188eu 的日志

    不对,我搜了一下这个型号有三种芯片,lz 这个就是 mt7601u 的,那不能按照那个教程走了,我上面这条回复也别理了,如果你执行了那条命令请执行下面的还原:
    sudo rm /etc/modprobe.d/blacklist-mt7601u.conf

    mt7601u 这个芯片的驱动我只搜到了针对 4.4.3 以下内核的驱动……不清楚有没有更新的
