新しいインターネット接続に問題があります。これは対称的な500Mbs接続ですが、Linuxシステム(fedora 30)では50Mしか入手できません。 Windowsでは、他のコンピュータとのトラフィックは500Mbです。私はイーサネットカードの速度が100Mbであるため、私のLinuxイーサネット接続に問題があることを知っています。理由はわかりません。
イーサネットカードの値です。 (1Gb対応)

ethtoolを使ってみましたが、1000Mb / sに変更しようとすると
$ sudo ethtool -s enp3s0 speed 1000 duplex full

しかし、リンクは接続できません。
enp3s0を増やそうとすると、1000Mbの速度が消えて再び100Mが出ます。
$ sudo ifup enp3s0

私は何をもっと試すべきかわかりません。
