No WiFi in Win10 Pro (1903) Windows Sandbox

I didn't have any WiFi icon within the Sandbox. I have it outside the Sandbox, which is how I'm connected to the internet to post here.

Until I am able to launch Sandbox (see above error message) the whole thing is on hold, anyway.

So you have the "wifi sandbox" adapter activated but not the actual Sandbox app working?
I have the opposite problem: I can start Sandbox but I have no connection in Sandbox itself, which makes it basically useless!
Frustrating.

No, I don't have a "wifi sandbox" adapter activated. Or, at least I don't think I do. There was no WiFi icon in the task bar in the Sandbox, and on the Network & Internet Settings panel from the Sandbox, WiFi was mentioned no place at all.

You have the same issue I had: no connection in the Sandbox itself. It's just that now, I can no longer even open the Sandbox at all...

Seems to be the case for 19.03, but you have a new error.

I just tried to "bridge connections" between vEthernet and WIFI adapter and something happened...... Microsoft Edge did not give me errors but I could not load any site. Just the spinning circle.....

OK, if you Bridge connections between the WIfi Adapter and the vEthernet Hyper-V Virtual adapter you get a connection, extremely slow but at least something!

Sounds good. Now, if I can ever get Sandbox to open again, I'll come back and ask your for directions on how to bridge those connections...

Hello, again. OP here. I wiped my hard drive and reinstalled Windows fresh and there is no problem with Windows Sandbox now: it loads properly and I have a working internet connection within it.

The first time I launched the Sandbox, it took a while for the internet connection to be established, but since then, each time Sandbox launches the internet connection is there. I was kind of expecting it to show a WiFi symbol, since that's how the computer is connecting, but it shows up as an Ethernet connection.

Yes, that's the same for a Hyper-V VM. The WiFi connection of the host machine is provided to the VM (or in your case, Sandbox) by means of a bridging switch. That appears as an Ethernet connection to the VM/Sandbox.
