I have 2 tlc/roku TV's. Every time I turn them off and turn them back on I have to check connection/set up connection. This is very annoying. My wifi strength is great and these are the only devices having issue. Please help!!
Go into the Power settings and enable "Fast TV start". It should maintain the Wi-Fi connection.
If your similar to alot on this forum my friend you will soon find out ROKU sucks. It has forgotten the WiFi connection on bout 100 other people, and that's just what I read.
Alot of people are just switching to FireStick.
Good luck.
