以太网速度仅为 100 Mbps

以太网速度仅为 100 Mbps

我目前正在使用 Pop!_OS，不幸的是我遇到了以太网连接问题：

我的 Pop!_OS 上的互联网速度上限为 100 Mbit/s。我的 ISP 的互联网速度为下行 200 Mbps，上行 8 Mbps，所以这不是问题。同样在 Pop!_OS 之前，我使用 Windows，下行速率为 200 Mbps，上行速率为 8 Mbps。它也是有线连接，因此大多数时候应该相当稳定。

我的主板 (MSI B550-A Pro) 中的以太网控制器是 Realtek® 8111H 千兆位 LAN 控制器。

我已经做了一些研究，但无法真正找到解决方案。

我希望你可以帮助我！

编辑：我通过在网络设置中禁用 IPv6 并重新启动来修复它。现在它显示 1000 Mbit/s，而不是 100 Mbit/s，而且现在也是全速。

答案1

Link partner advertised link modes:  10baseT/Half 10baseT/Full
                                     100baseT/Half 100baseT/Full

这是远程端报告的它将支持的内容。由于没有1000baseT/Full选项，这里网络电缆远端的设备告诉它不支持千兆位连接。

当您禁用 IPv6 时，您是否也以任何方式更改了网线？例如，您是否将其插入调制解调器的不同端口？也许只有部分端口具有千兆位能力。

答案2

我尝试过禁用 ipv6，但这对我不起作用。我的问题是由“powersave”调整配置文件引起的，该配置文件将 NIC 置于 100MBps 模式。

要检查您的调整配置文件，请运行sudo tuned-adm active.如果返回“powersave”，则将其更改为默认值sudo tuned-adm profile balanced
