I have a Roku Streaming Stick and every time it is powered on it’s a 50/50 chance it will connect to wifi. Once the Home Screen loads and the display shows “not connected” the only thing to do is power back down and try again over and over until it finally connects. The remote does not work at all at this point. I have tried resetting my modem and checked for a stable connection on other devices however it seems that the Roku is where the problem is. Any ideas on how to fix this?
If you're using the TV's USB port for power try using the supplied power adapter so the stick doesn't have to restart every time you turn on the TV. Instead of powering down have you tried just going through the network setup again? I have multiple devices that don't like something about my network and show "Not connected" even though they definitely are. I have to go through the network setup every time they restart to make them happy.
