我昨天启动了笔记本电脑，但无法连接到互联网（通过 Wifi）。它可以使用我的 Handy Hot Spot 和以太网连接（使用我拥有的互联网）。我还尝试了另一个 WIFI，但同样不起作用。然后我尝试重新启动系统，但系统显示：“无法启动 Networkmanager”。在 Windows 上，网络连接正常。这是我的 Networkmanager 日志：

what can i do now?
答案1
我不知道如何解决这个问题，但我有一个解决方法，我正在使用这种方法来解决同样的问题。我在启动时从 grub 菜单中选择内核 6.2.0-39，将其恢复到内核。使用任何 6.2.* 内核时，wifi 都可以工作，但使用 6.5.* 版本时不行。
如果你已经自动删除了 6.2 内核，你可以使用以下命令再次安装它们
sudo apt install linux-image-6.2.0-39-generic
