即使路由器重新配置后，Ubuntu Wifi 仍会不断重新连接

我安装了 ubuntu 20.04，对于特定的 Wifi 连接（我家里的那个），我遇到了以下问题：wifi 会在一段时间后（大概每 3 或 5 分钟）断开连接并重新连接。

这是我所做的：

  1. 我将路线设置更改为如下：

  1. 我检查了我的 iwconfig 输出：如下所示，电源管理已经关闭

在其他任何 wifi 连接中都不会发生这种情况，我的 Windows 和 Android 设备在同一个 Wifi 网络中运行正常。我必须进行什么配置才能让我的 Ubuntu 在 wifi 中运行吗？

答案1

根据tail -f /var/log/syslog路由器配置的输出和更改，我假设网络管理器中的 WiFi 配置未正确更改。 解决此问题的方法很简单，只需：

  1. nm-connection-editor在终端上打开
  2. 选择并删除 WiFi 连接
  3. 从一开始就连接到同一个 WiFi

答案2

嗎答案正确。

我只想添加一个步骤：重新启动 NetworkManager。只有完成这一步后，我的网络才能恢复稳定。

我正在使用带有 MESH 设置的 20.04.5 LTS。
