Gregory's ServerSeen via a post on discord - HiSense smart TV borks user's computer, bluetooth due to frankly insane UUID generation spamming the local network.

This kind of thing is why I haven't bought a new TV, even though I want one and can afford one, I want a dumb one and this seems almost impossible. Even if I got one and didn't give it direct network access, I'm not sure I'd trust it not to sneak online using HDMI and connect via more trusted devices...
@edchivers I went with an LG G3 and it works well with no network access. (Not sure about the G4 series though.)
