Disabling ads is easy, don’t connect it to the internet ever

Any way to connect it to an internal network so I can still cast from local devices? Otherwise it’s just going to exist plugged into a laptop.

Something like a chromecast would be the easiest solution.

Me personally, I just like having a media pc hooked up to my tv. I bought an amazon fire tv cause it was fairly cheap for 4k and its never been hooked up to the internet.

Just watch them serve ads on those too
