我知道有很多帖子试图解决该问题，但到目前为止对我没有任何帮助。

以下是日志的一部分sudo journalctl -b 0 -u NetworkManager

我似乎在这里找不到任何相关信息，所以问题可能来自固件？但我不知道该卸载哪一个等等……
答案1
噁心！日志呕吐！
通过以下日志，似乎成功建立了 IPv4 DHCP 连接（“ manager: startup complete”。然后，在[1684986907.8166]（自启动以来的时间 秒数.纳秒）时，dhcp6尝试建立 IPv6 连接，失败，并让接口等待 DHCP6 响应。
如果您不打算使用 IPv6，则应该禁用 IPv6。
系统设置->网络->点击设备
如果您有意使用 IPv6，则您的 DHCP 服务器存在问题。
