LAN (wired network) stuck on Identifying Network…are you running Virtual Box as well?

Had a weird one yesterday that stumped me.

For the life of me, I couldn’t connect to my second sub network in my house, which has my private server lab in it.

Whenever I plugged/unplugged the cable, DHCP wouldn’t work. Static IP set didn’t work either.

I would get a message next to the adapter saying stuck on Identifying Network.

Then I realised I had disabled the “VirtualBox Host-Only Network” adapter, just because I’m not using it currently. I enabled it, then replugged my cable and everything was fine.

So Clearly there is a bug there.

What was odd was my other Ethernet adapter was fine the whole time.
