WSL2 网络不可访问

我的 WSL2 无法在任何发行版上连接到互联网。无法访问网络sudo apt-get update。我没有任何 VPN，只有全新的 Windows 11 或 10。它是使用 Wifi 路由器的有线连接，如果我直接从 wifi 使用有线连接，它可以连接到互联网Onu设备设备而不是路由器。类似于下图：

有线连接

现在它来自下面的 Wifi 路由器： 通过路由器有线连接

这是我的ipconfig输出： ipconfig 输出

OS: Windows 11 (Up to date)
Distro: Ubuntu (WSL 2)

我尝试过但失败了的事情：

答案1

我遇到了同样的问题，当我在以太网属性中关闭 ipv6 协议后，问题就解决了。

--编辑-- 请注意，这不是永久/“真正的”解决方案。它似乎仅在您禁用 ipv6 后才有效。

答案2

对于我来说，启用镜像网络模式解决了连接问题：

编辑%UserProfile%\.wslconfig以包括：

[wsl2]
networkingMode=mirrored

然后使用 重新启动发行版wsl --shutdown。根据https://learn.microsoft.com/en-us/windows/wsl/networking#mirrored-mode-networking这有以下好处：

  • IPv6 支持
  • 使用本地主机地址 127.0.0.1 从 Linux 内部连接到 Windows 服务器
  • 改进了 VPN 的网络兼容性
  • 多播支持
  • 直接从局域网 (LAN) 连接到 WSL

答案3

除非配置损坏，否则 WSL2 会连接到互联网。

虽然实现这一目标最健康的方式可能是阅读WSL2 文档非常小心地、一步一步地去做，我认为我对自己最近的经历的思考可以在经验层面上有所帮助。

正如一些评论所述。WSL 和 WSL2 的网络连接不同，当 WSL 直接作为桥梁工作时，它与 WSL2 Nat 或类似机制一起工作。（向后兼容的一个很好的例子！）

在使用 WSL2 尝试了几次失败后，我遇到了同样的情况，经过研究并再次尝试，我发现如果有必要，我可以设置 WSL 发行版或一般的 WSL 版本。

wsl --set-version <distro name> 2

wsl --set-default-version 2

WSL --> WSL2 版本混淆可能会导致问题。

Hyper V 为 WSL 和 WSL2 添加了一些适配器。我尝试编辑网络适配器，因为添加的 HyperV Bridge Adapter 样式设备影响了我的 IP 寻址系统，我开始在网络上遇到问题，并开始摆弄设置。此时我失去了 WSL2 的互联网输出。当我通过 HyperV 重新创建网络适配器时，问题就解决了。如果您可以检查网络适配器并详细检查它们 - IP 地址、网关等 -

随着时间的推移，如果确实需要，我们可能有机会创建一个可行的示例视频演示。

答案4

无法下载任何 apt 更新/升级。总是超时。

  • WSL2 LTS 22.04.1
  • IP正确
  • DNS 工作

问题出在 WSL2。轻松修复。

在 DOS 命令提示符下

wsl -l -v

获取发行版名称：

wsl --set-version <distro name> 1

需要几分钟才能连接到 v1。

重新启动后一切就都正常工作了。
