Wi-Fi & connectivity

[Cooper333]

I see some similar posts but none answer my problem. Yesterday upon turning my tv on, everything was normal. Then as soon as I chose what I wanted to watch I get “not connected to wifi” pop up. 
turned everything off and rebooted my router. I had to manually add my wifi info. And it worked for like 5 minutes. Now when I try to get on my tvs not recognizing my roku at all. Nothing has changed. My router is testing fine. I’ve only had this for about a year. And this device is not eligible for support. Which is total bull sh!t.

What's the model number written on the device somewhere?  If you're using the TV's USB port to power it, try a USB power adapter/charger from a phone or tablet that can provide at least 1 Amp.
