You can just remove the wifi module. Lay the TV on its face on a piece of cardboard on the bed. Remove the back, locate the wifi module, remove it, and Bob’s your uncle or something.

Seriously, it can’t access the internet if it doesn’t have an access point.

As for the computer connected to your television and it’s access point, it’s simple not to connect a Windows computer to a TV. Most any windows compatible computer you’d do that with can run Linux and if windows is going to allow this kind of nonsense they don’t deserve your business or your data.

I absolutely know my take is the view of someone who’s tech savvy enough to do both things.

I get that for the last 30 or so years I have been the tech support for basically my entire family and some of their friends.

But if it’s going to be basically impossible to buy a dumb TV and expensive as all get out to do it, it’s time to find that tech savvy person you know and ask for help because otherwise this will keep happening.

As a former IT professional, it blows my mind that people actually hook their TVs up to an Internet connection. Why would you ever want your TV installing updates? Or for that matter, give it the chance to install malware? Not to mention, the potential for it to turn on a microphone (!?) and listen to you in your home! Why does a TV have a microphone built in?! A TV should never be able to record you!

I bought a mini PC and hooked it up to my TV. It’s not that powerful, but it can stream 4K video through a web browser. I use a wireless mouse and keyboard on my couch to access it

Because it’s a PC, I can install ad blockers and other security features to keep junk from popping up while I’m using it. Then I just stream all my shows and whatnot, fullscreen through the browser. No interruptions, total control over what is installed/playing, and the TV itself doesn’t connect to the Internet. It’s just a dumb device, acting like a monitor.
