I don't see network anywhere. Maybe you wanted networkingMode?

[diehard2]

@aentwist sorry, it was a typo in my issue title.

I updated to 2.0.14 and I am seeing the same issue

ping: google.com: Temporary failure in name resolution

just nothing at all in mirrored

I am having the same issue - if I enable networkingMode=mirrored I can do DNS (probably because I turned on the dnsTunneling) but cannot connect/ping any IP except my PC's own IP

[chanpreetdhanjal]

Please follow the networking diagnostic script. https://github.com/microsoft/WSL/blob/master/CONTRIBUTING.md#collect-wsl-logs-for-networking-issues

It should create a folder like [WslNetworkingLogs-date_ver.zip]

As a workaround I disabled systemd-networkd with sudo systemctl mask systemd-networkd.
