我用的是这个驱动程序:
https://github.com/clnhub/rtl8192eu-linux
它运行得很好,但有时过了 2 或 3 周后,wifi 适配器就无法再识别了,我需要重新安装驱动程序,然后它才能正常工作。
可能是什么原因?与 Ubuntu 更新有关吗?

由于您安装驱动程序的方式,每次通过软件更新程序更新内核时都需要重新安装您的 wifi 驱动程序。
您需要按照dkms
安装说明来修复此问题。请参阅 README.md...
手动安装
使用以下命令删除可用的驱动程序(如果 sudo lshw -C network 和 dkms status 没有显示任何 wifi 驱动程序则跳过):
sudo rmmod 8192eu
sudo rmmod rtl8xxxu
sudo dkms remove rtl8192eu/1.0 --all
黑名单默认驱动程序(Ubuntu 上的 rtl8xxxu):
echo "blacklist rtl8xxxu" >> ./blacklist-rtl8xxxu.conf
sudo mv ./blacklist-rtl8xxxu.conf /etc/modprobe.d/
从驱动程序目录运行添加并安装命令:
sudo dkms add .
sudo dkms install rtl8192eu/1.0
加载驱动程序(或重新启动):
sudo modprobe 8192eu
然后,dkms status
应该显示rtl8192eu驱动程序已安装。
