@johnefrancis @arstechnica Mine are both a bit older too. One is connected but the other is not, because it becomes almost non-functional when it is disconnected. I'm replacing my home routing setup with something a bit more sophisticated, and I'm going to see how well the router's ad-blocking DNS works on the TV.
It's such a shame that the Digital Milenium Copyright Act makes it nearly impossible for anyone to create an open-source TV OS to replace the bloatware TV manufacturers ship.
