我已经使用这款笔记本电脑一年多了,Ubuntu 20.04已安装。无线网卡Wi-Fi 6 AX200自从上周更新 ubuntu(我经常运行sudo apt update
)以来,WiFi 就无法连接,即使我输入了正确的密码,它也会一直要求输入密码。但是,如果我以恢复模式启动,修复软件包并重新启动,WiFi 问题就会得到解决,但仅限于该启动。在下一次启动时,问题又出现了,我不得不不断重复恢复模式步骤,但是在这个模式下,正如预期的那样,多个功能被禁用(尤其是 X,所以我无法改变屏幕亮度,这让我的眼睛很难受 T_T)。请帮忙找出 wifi 的问题。
事件发生前,Snap 还发送了一些消息,我记不清了,但我怀疑这可能是问题所在。不过,我可以在正常启动时通过 LAN 连接。
附加输出sudo lshw -C network
