i changed the networkingMode in .wslconfig, made the value nat, and now the network is working. 😎

it's workin' okay now. Maybe Windows 11's update has changed the mirrored network. I don't wanna spend much more time on it. So, it's done!

The LAN cannot access the network of WSL.

I may have found the problem，but i can't take it over. My computer has two network cards. One is built into the motherboard, and the other is a USB Wi-Fi network card. After a certain system update, the mirrored mode broke down and my motherboard's built-in network card could not be loaded. After I disabled it, WSL could start normally and the network was also normal. If only the motherboard network card is retained and my Wi-Fi network card is disabled, there will still be an error when starting up and there is no network. My motherboard network card is Realtek RTL8168/8111/8112 Gigabit Ethernet Controller/Asrock. The Windows version is Microsoft Windows version 22H2 (OS internal version 22621.3527).

我也许找到了问题，我的电脑有两张网卡，一张是主板自带的，一个是usb wifi 网卡，某次系统以后，mirrored模式就坏了，无法加载我的主板自带的网卡，我把他停用以后，wsl就可以正常启动，网络也是正常的。如果只保留主板网卡，停用我的wifi网卡，启动还是报错，没有网络。
我的主板网卡是 瑞昱RTL8168/8111/8112 Gigabit Ethernet Controller/华擎，window版本是Microsoft Windows版本22H2(0S内部版22621.3527)

@CatalinFetoiu can you take a look?

@lifetraveler thanks for reporting the issue
from the logs in your initial comment, I see generateResolvConf is set to false in your /etc/wsl.conf, while dnsTunneling is set to true in wslconfig. generateResolvConf needs to be true (or default, which is also true), in order for dnsTunneling to be successfully enabled

can you please try setting setting generateResolvConf to true, then run "wsl --shutdown" and restart WSL? let us know if you still encounter DNS issues after doing this
