USB 以太网连接时 Wi-Fi 断开连接

正如标题所述，只要 USB 以太网连接，WiFi 就会断开连接。我的以太网连接提供互联网，WiFi 可访问 LAN。去年它一直正常工作，但突然停止了。

以下是以下命令的输出：

$ nmcli device

有任何想法吗？

答案1

问题是您的 wifi 和以太网位于同一子网。wifi 实际上并未被丢弃，而是被降低了优先级。

您有两条到 192.168.10.0/24 的路由和两条默认路由。

您可能能够通过调整两条路线的优先级来解决此问题。

如果这些实际上是独立的网络，则您应该更改其中一个的子网地址，使它们不同。 （即 192.168.1.x）（如果这样做，您必须为该网络上的每个设备更改它，而不仅仅是您的计算机。）
