我的新互联网连接有问题。这是一个对称的 500Mbs 连接，但我在我的 Linux 计算机（fedora 30）中只能获得 50M。在 Windows 中，我与其他计算机的上下流量为 500Mb。我知道问题出在我的 Linux 以太网连接上，因为我的以太网卡速度是 100Mb。我不知道为什么。
这是以太网卡值（支持 1Gb）

我尝试使用 ethtool 但当我尝试更改为 1000Mb/s 时
$ sudo ethtool -s enp3s0 speed 1000 duplex full

但我没有得到链接连接
如果我尝试提高 enp3s0，1000Mb 的速度就会消失，然后我会再次获得 100M
$ sudo ifup enp3s0

我不知道还能尝试什么。
谢谢
