我的 WiFi 在 2019 年 9 月 23 日停止工作,我试图找出发生了什么变化,它似乎可以在内核版本 4.15.0-60-generic 下工作,但在较新的内核 4.15.0-64 下失败。知道原因或该怎么办吗?
我的设置细节:
操作系统:Ubuntu 18.04.3
网络驱动程序:iwlwifi
lspci 与工作内核:
$ lspci -nnk |grep Network -A3

rfkill 输出:当它工作时(旧内核):
$ sudo rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN

当它不起作用时(新内核):
$ sudo rfkill list

Hard blocked: no
答案1
这可能是内核错误。最简单的方法是升级到 HWE 内核。
在终端中运行
sudo apt install linix-generic-hwe-18.04
然后重新启动。
