Killer E2400 千兆以太网控制器不工作

我的 Killer E2400 千兆以太网控制器和 BCM4360 802.11ac 无线网络适配器突然停止工作,而且我无法让它再次工作。

输出lshw -C network为:

ubuntu版本是22.04 LTS(jammy)

我尝试按照这篇文章的建议在 BIOS 中禁用 IOMMUKiller Ethernet E2400 未连接 16.04

这是的输出sudo modprobe alx

modprobe: FATAL: Module alx not found in directory /lib/modules/5.15.0-43-generic

答案1

当启动到以太网可以工作的早期内核版本时,打开终端并执行以下操作:

sudo apt update
sudo apt install --reinstall linux-modules-extra-5.15.0-43-generic

重启。一切就绪。
