[WSL2/Ubuntu] Can't connect to internet

[kidapu]

I read the following similar issues, but I guess my problem is different from them.

• [WSL2/Ubuntu/Debian/Kali] Network not configured #5286
• wsl2 no internet access (unable to resolve host address) on windows 1909 build 18363.1139 #6427
• https://github.com/microsoft/WSL/issues?q=is%3Aissue+is%3Aopen+label%3Anetwork

The following is a list of my situations.

(1) With WSL2, I can't ping with IP address.

$ ping 1.1.1.1
PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data.
( No response)

The difference from other issues is that DNS seems to be working effectively in WSL2.

$ nslookup google.com
Server:         172.26.112.1
Address:        172.26.112.1#53

Non-authoritative answer:
Name:   google.com
Address: 172.217.161.78
Name:   google.com
Address: 2404:6800:4004:80b::200e

(2) Convert to WSL1, the ping will work

$ wsl --set-version Ubuntu 1
$ wsl 
$ ping 1.1.1.1

(3) Network status

In WSL2

My environment is below.

• Windows : 10.0.19042 Build 19042
• Installed Ubuntu and Ubutnu 18.04 . Both had the same problems.
• I'm not using VPN.

I never successful connect to
Failed to fetch http://archive.ubuntu.com/ubuntu/dists
if using WIFI at home (no VPN).

I have edited the /etc/wsl.conf and /etc/resolv.conf to contain same nameserver as my WIFI router box

@asampadeh
In my case, DNS is working.
But the network is not connected.
I think editing /etc/wsl.conf and /etc/resolv.conf does not work for me...

$ ping archive.ubuntu.com
PING archive.ubuntu.com (91.189.88.152) 56(84) bytes of data.

After running the commands in the comments below, my PC stopped connecting to WiFi, not just WSL2.

I had to reinstall the drivers and no matter what I did, I could not get it fixed to the internet.

Therefore, I reinstalled Windows 10.

After that, I was able to connect to the Internet even with WSL2....

oh boy. I have confirmed that I can reach the internet using WSL1, but not WSL2. I performed the same steps in your description. I can't re-install windows as it's a company-controlled install so I get provided an "image" with pre-installed windows. :/
