Linux ubuntu 桌面卡在 100Mbps

Linux ubuntu 桌面卡在 100Mbps

我在家里使用华硕 z490 strix e 和 Linux ubuntu 桌面 20.04,我家里有 3 台电脑,2 台 Windows,速度为 1Gbps,但我不知道为什么我的 ubuntu 桌面无法达到 1Gbps。我的 netgear 路由器在 LAN 端口附近有一个橙色指示灯,该 LAN 端口连接到我的 Linux 计算机,这表明与 ubuntu 桌面的连接出现了某种问题,其他计算机是白色指示灯,因此没有连接问题。

我尝试阅读一些网站并在谷歌上搜索有关这个问题的信息,但到目前为止它们都对我不起作用,我不知道下一步该怎么做。

以下是来自 Linux 桌面的一些信息

请帮我
