Lossing internet connection when some commands are run.

[fprin]

Environment

Windows build number: Microsoft Windows [Version 10.0.20201.1000]
Your Distribution version: Release:        18.04
Whether the issue is on WSL 2: Linux version 4.19.104-microsoft-standard (oe-user@oe-host) (gcc version 8.2.0 (GCC)) #1 SMP Wed Feb 19 06:37:35 UTC 2020

Steps to reproduce

So, as usual, I lost internet connection from inside of WSL terminal. I follow this: #3438 (comment)

netsh winsock reset
netsh int ip reset all
netsh winhttp reset proxy
ipconfig /flushdns

After reboot, I am able to get access to internet again.

Then, I try to push a new branch to github and I lost internet conneciton again.

ping github.com # it will work without problem after the reboot
git push -u origin your_branch_name
ping github.com # it stopped to work.

WSL logs:
ping: github.com: Temporary failure in name resolution

Expected behavior

Never lost internet connection when I execute some commands.

Actual behavior

I am always losing internet connection when I execute some commands.

Please collect WSL logs and post the backlink to the feedback item here. Also list list your third-party networking software installed on Windows, if any.

It isn't clear from your post whether you're networking was taken down entirely, or whether names can't be resolved. If you can still ping (say) 140.82.114.3 but can't resolve github.com, you can try forcing the nameserver to 8.8.8.8 in /etc/resolv.conf, ref #4285 and friends.

I am also having this issue. Unable to ping anything including the host IP.

Ethernet adapter vEthernet (WSL):

Media State . . . . . . . . . . . : Media disconnected

The only thing that has fixed it was resetting my network settings (Windows Settings ->Network & Internet -> Network reset) and reinstalling WSL and Hyper-V. Probably pretty overkill, but it quit working shortly afterwards. I also have Docker Desktop installed and it is not having any issues.

@therealkenc right now I don't have too much time to collect the WSL logs, but the solution that you gave here #4285 doesn't work. I had already implemented that:

@isgallagher try to roll back to WSL 1, that fixed my problems with network. WSL 2 doesn't work.

# in your cmd windows shell, run it as admin.
wsl --set-version Ubuntu 1

@therealkenc it seems to be a duplicate of this one: #5821

I am having the same issue:

Could you please test this https://gist.github.com/danvy/9486bf730371436131cb888ff4c2ceb6 ?

[isgallagher]

@danvy that fixed it for me. I've tried restarting hns and lxssmanager before but didn't know about restarting the vEthernet adapter.
