我正在运行 18.04 服务器，最近我的 Netgear AC1900 wifi 卡停止工作。我不太确定发生了什么，但在深入研究之后，司机出了点问题。
我已尝试多次删除并重新安装驱动程序，但它仍然给我带来了麻烦。这就是我所在的位置：
我试过通过 dkms安装这个驱动程序（ https://github.com/zebulon2/rtl8814au.git ）。当添加和构建正常时，但当我去安装时，它说已经安装了一个更新的版本：“警告！构建和安装模块之间的差异！”
它从 lusb 显示为 0846:9054 NetGear，但从 ifconig 显示为 0846:9054 NetGear。
我确定我只需要正确删除其中的任何旧驱动程序，然后重新安装，但我不知道该怎么做。我一直在搜索帖子/在线无济于事。
建议？
先感谢您。
