In theory a neighbours lg tv could broadcast their wifi credentials to your tv to connect to upload the data.

but its technically doable.

Agree that mesh networking is technically doable. Credentials, IDK about that, but mesh, yes.

I thought I remembered a mfg who sold appliances that would try to mesh-network with others from the same mfg. Even if it was at another household or w/e.

But I can't seem to find the story now! IDK, maybe I'm fulla shit. Maybe I'm just jaded and my brain made it up. I'm trying to search but overloaded with pages about legit mesh networking.
