打开 Wi-Fi 面板后才能上网

打开 Wi-Fi 面板后才能上网

我在 Ubuntu 22.04 上的互联网连接方面遇到了一个奇怪的问题。

通常,当我连接到家里的 Wi-Fi 时,如果系统显示相反信息,互联网也无法工作。

我发现解决问题的唯一方法是打开右上角的 Wi-Fi 图标并选择语音“选择网络”。当选择网络的面板打开时,互联网确实会再次开始工作。请注意,面板打开后我没有点击任何东西,并注意它说 Wi-Fi 连接始终处于开启状态且稳定。

当这样做时,它会再次开始工作,但不到几分钟后,它就会再次停止。

这个问题只出现在我的 Ubuntu PC 上,并且只出现在使用我家的网络时;在其他设备上不会出现这种情况。重新安装一个全新的操作系统似乎也无法解决这个问题。事实上,我前段时间一直在运行 Kubuntu,也遇到了同样的问题。

此外,我没有改变任何网络配置或设置。

我该怎么做才能像其他人一样保持连接稳定?谢谢 :)

下面是我看到的运行“sudo journalctl -b 0 -u NetworkManager”的最后几行,我注意到这些是周期性的:

是否有任何信息可以找到问题的根源?谢谢!
