以太网-速度只有100 Mbps

Question

我目前正在使用Pop!_OS，不幸的是，我的以太网连接遇到了问题：

我的网络速度-在流行！_OS被限制在100 Mbit/s。我的互联网速度从我的ISP是200 Mbps在下游和8 Mbps上流，所以这不是问题。同样在Pop!_OS之前，我使用了Windows，下游有200 Mbps，上游有8 Mbps。这也是一个有线连接，所以它应该是相当稳定的大部分时间。

我的主板中的以太网控制器(MSI B 550-A Pro)是Realtek 811 1H Gigabit LAN控制器。

我已经做了一些研究，但没有找到真正的解决办法。

我希望你能帮我！

编辑:我通过禁用网络设置和重新启动中的IPv6来修复它。现在显示的是1000 Mbit/s，而不是100 Mbit/s，而且现在还有全速。

Answer 1

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

这是远程终端报告将支持的内容。由于没有1000baseT/Full选项，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络电缆？例如，您是否将其插入调制解调器中的另一个端口？也许只有几个端口能够达到千兆位。

Answer 2

我试过禁用ipv6，但这对我没有用。我的问题是由“节能”调优配置文件引起的，这使NIC处于100 mode模式。

要检查您的调优配置文件，请运行sudo tuned-adm active。如果返回"powersave“，则将其更改为默认的sudo tuned-adm profile balanced。
