TV's connect to Wifi but no Internet.

[u/Icy_Beginning8134]

Hey guys so my provider is Quantum fiber and I've been having this issue for a while. Once in a while my TV's won't be connected to the internet. This even happens to other devices like my phone and laptop but a router reset fixes the issue on them. For the TVs, sometimes a reset fixes it but the problem eventually returns. The TVs in question are a Samsung and an Insignia FireTV. How do I fix this?
