WSL vEthernet adapter shows up as disconnected after the latest Windows 10 update (10.0.20197.1000) ## Environment ```bash Windows build number: 10.0.20197.1000 Your Distribution version: Ubuntu 20.04 The issue is on WSL 2. ``` ## Steps to reproduce 1. Start using Ubuntu on WSL2: works fine 2. After an arbitrary amount of time, no longer able to access the network. 3. `ipconfig` on Windows shows ```bash Ethernet adapter vEthernet (WSL): Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : ``` ## Expected behavior Network access should be available. ## Actual behavior As the adapter is disconnected, cannot access the network from inside WSL. This issue did not exist prior to installing the latest Windows update from the dev channel. Requires a Windows restart to restore network access, but the adapter disconnects once again arbitrarily. Putting the laptop to sleep and waking it up almost always causes the adapter to show up as disconnected immediately. Does not seem to be related to the use of a VPN although I use one (via the OpenConnect client).
