最近更新后，我的 Ubuntu 22.04 中的 Wifi 停止工作。查看 UI 时，它显示已连接到 Wifi，但我无法访问互联网，并且在 ping 任何内容时都没有响应。
我尝试通过电缆和另一个 USB Wifi 适配器进行连接，但都不起作用。我还尝试将内核降级到以前的版本 (5.13.0-46)，但没有成功。
这是我的一些日志

我真的不确定为什么会发生这种情况，因为对我来说似乎一切都正常并且内核模块已加载。（至少对我来说）
如果在调试问题时遗漏了任何相关内容，请告诉我。任何帮助都非常感谢。谢谢！
答案1
经过一番调查，我解决了这个问题。Iptables 阻止了流量。这是由 Nordvpn 终止开关引起的，我试过一次。重新启动 nordvpn 并重新连接解决了这个问题。
感谢大家的帮助。
