I have a similar problem with the Roku Streaming Stick+ in my living room which is in nearly constant use during waking hours. I lose my WiFi connection on this unit several times a month and have to re-establish the connection. The seldom used Streaming Stick in our guest room has never lost connection that I can recall. Our TCL Roku TV in the bedroom has lost connection perhaps twice in the last year or so.
I suspect this has something to do with some sort of instability in my old Western Digital router (WD got out of the router business several years ago). I'm guessing an occasional glitch of some sort that the Roku can't recover from causes it to lose connection and then refuse to connect again. I further suspect this also only happens when the Roku is actually streaming something as it is most prevalent on my most-used unit.
At any rate, I've gotten pretty proficient at getting the connection set back up, as follows:
- Restart your router (even if other devices have no problem finding and connecting). Sometimes that's all it takes, if not keep going.
- Restart the Roku to clear its memory via Settings > System > System restart (for a Roku TV it's Settings > System > Power > System restart). Again sometimes that's all it takes, if not keep going.
- Find and connect to your network via Settings> Network > Set up connection
If that doesn't fix it, try disconnecting the power to your Roku for a few seconds. When it comes back up, see if you then can set up the network connection.
