定义固定以太网 IP 地址后无法访问互联网

2024-6-8 • tag-icon

我为某个项目为我的以太网连接分配了一个固定 IP 地址。从那时起，我的 Wifi 就变得非常慢，有时我甚至无法访问网页。由于我不是这方面的专家，所以我可能改错了什么，但我不知道是什么。我有以下设置ubuntu@master:~$ ifconfig：：

wlp65s0我的 WLAN 互联网连接在哪里？在我进行一些更改之前，它工作正常。我的以太网连接在哪里enp4s0？我也有sudo nano /etc/network/interfaces

auto lo
iface lo inet loopback

#this has been added:
    allow-hotplug enp4s0
    iface enp4s0 inet static
    address 192.168.1.1
    netmask 255.255.255.0
    network 192.168.1.1
    broadcast 192.168.1.255

然后：sudo nano /etc/netplan/01-network-manager-all.yaml

network:
  version: 2
  renderer: networkd #before, this was NetworkManager
  ethernets:
    enp4s0:
      addresses: [192.168.1.1/24]
      gateway4: 192.168.1.1
      nameservers:
          search: [255.255.255.0]
          addresses: [1.1.1.1, 1.0.0.1, 192.168.1.1]

ls -al /etc/netplan：

total 20

您能否指出您发现的不一致之处？如果有任何遗漏或不清楚的地方，请告诉我。任何提示或帮助都将不胜感激。我有 Wifi 卡 Aorus GC-WBAX200，正在 Ubuntu 18.04 桌面上运行。提前非常感谢

对于 Ubuntu 桌面...

您的 /etc/network/interfaces 应该是：

auto lo
iface lo inet loopback

您的 /etc/netplan/01-cloud-init.yaml 应该是：

network:
  version: 2
  renderer: NetworkManager

sudo netplan generate

sudo netplan apply

reboot

然后使用 NetworkManager GUI 设置静态地址（如果需要）：

注意：静态地址不能是您的路由器的地址（192.168.1.1）。
