当我在 Ubuntu Server 20.04 中使用 Netplan 设置静态 IP 时，我遇到了互联网速度问题。

我使用的是戴尔 PowerEdge R710，没有 wifi 卡，所以我在论坛中找到的所有涉及 wifi 的解决方案都不起作用。我还尝试了 Netplan 中的一些其他配置以及我在论坛中找到的其他建议，但它确实没有用。

如果我禁用静态 IP 并让它动态，互联网速度就可以了。有谁知道如何解决这个问题？

这是我的50-cloud-init.yaml

aiec@camera02:/etc/netplan$ sudo nano 50-cloud-init.yaml
network:
  renderer: networkd
  ethernets:
    eno1:
      dhcp4: no
      addresses: [192.168.253.188/24]
      gateway4: 192.168.253.1
      optional: true
      nameservers:
        addresses: [8.8.8.8,8.8.4.4]
  version: 2

速度测试结果（如果我使用动态 IP，速度会达到 40~45 Mbits/s）
