Mon*_*sto 7 wireless networking internet ethernet 22.04
从 20.04 升级到 22.04 后，网络无法工作，直到我发出
sudo nmcli networking off && sudo nmcli networking on
对于以太网/有线和 WiFi 以及来自终端的 ping 都是如此。我在 Lenovo X230 笔记本电脑上运行 Ubuntu 22.04。
也许相关：当使用 Ubuntu 20.04 时，网络可以在启动时工作，但是当我从有线切换到 wifi 时，反之亦然，我需要使用上述命令重新启动 NetworkManager。在 22.04 下，网络在启动时无法工作，直到重新启动为止，并且我需要在切换时重新启动。
我可以通过将其添加到登录中来破解它，但我确信如果我找不到根本原因，它稍后会咬我。
sudo journalctl -b 0 -u NetworkManager这是网络不工作时启动后的结果。这是使用关闭 wifi 的有线连接，由 sw rfkill 确认：
