That won't save you anymore. My boss bought a smallish smart TV in contravention of my explicit instructions for use as a CCTV monitor because it was "cheap." It nags you on power up with a popup whining about not being able to access the internet, and if you don't feed it your Wifi password it will subsequently display that same popup every 30 minutes or so requiring you to dismiss it again. And again. And again. Apparently the play is to just annoy you into caving and letting it access your network.
Instead I packed it up and returned it. Fuck that.
