我是 Linux 新手。我在计算机上安装了 Ubuntu 18.04.1 和 Windows 10。大约一周以来,一切都运行顺利,然后突然间,网卡就死机了。安装固件并重新启动网络管理器后,仍然无法通过 BIOS、Windows 或 Ubuntu 访问该卡。我甚至看不到它。
所以我从戴尔买了一张新卡(因为笔记本电脑仍在保修期内),但他们只有同一张卡可以替换。现在,我有蓝牙,当我启动 Windows 时,卡可以正常工作。然而,在 WiFi 下,它仍然显示没有 WiFi 适配器。
有人可以帮忙吗?

我认为你的内核更新有问题,请尝试
sudo apt install --reinstall linux-modules-extra-$(uname -r)
