Windows Version

Microsoft Windows [Version 10.0.22621.1413]

WSL Version

1.2.0.0

Are you using WSL 1 or WSL 2?

• WSL 2
• WSL 1

Kernel Version

5.15.90.1-microsoft-standard-WSL2

Distro Version

Ubuntu 20.04

Other Software

No response

Repro Steps

behavior is same on each system reboot

Expected Behavior

wsl network adapter would get new ip on reboot, thus ubuntu would also get a new ip

Actual Behavior

On each reboot, the wsl network adapter retains the same ip address of 172.30.224.1. this causes various connectivity issues within ubuntu. The largest issue is that i can no long connect to the smb on my ubuntu distro. One interesting thing I noticed was when checking the 'neighbors' via ipconfig for the wsl adapter it shows the ubuntu ip (172.30.233.201) as 'stale'

Today I found that the "vEthernet (WSL)" adapter is also missing from the "Network Connections" adapters in the Control Panel. It used to show up there. I'm wondering if some configuration is now missing.
