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.

It’s a 3900X.  I plugged the usb directly into an adapter into a wall socket. After I got a pop up about not enough power. Still Not able to locate my wifi.

Hello! @Cooper333,

Thank you for posting in the Roku Community!

We appreciate you reaching out to us about the low power issue. We are happy to help.

If you are connecting your Roku player to a power outlet, try the following steps:

1. Use a power adaptor
   • If your player included a power adaptor in the box, only use the power adaptor provided.
   • Using a different power adaptor, even one used with another streaming player, maybe the reason that your player will not power on.
   • If your streaming player did not come with a USB power adaptor, a USB power adaptor with a power output of 5 Volts, 1 Amp (1000 mA) will provide sufficient power.
2. Securely attach the power adaptor
   • Remove and reattach the power adaptor making sure it is securely and firmly connected to the streaming player and the wall power outlet.
3. Try a different power outlet
   • Try connecting the power adaptor to a different power outlet.
   • Alternatively, you can try testing another electronic device you know works in the same power outlet.
   • If your streaming player is connected to a power strip, unplug it and connect the power adaptor directly to a wall power outlet.
4. Check the light
   • In the rare case that the light on your streaming player is not functional, learn what to check if you cannot see the video on the TV.
5. Try the USB port on your TV
   • If your streaming player supports USB power, then try connecting it to the USB port on your TV using the USB cable that came with your device.
6. Disable auto power savings
   • If you are unable to "wake up" your streaming player using your TV remote, you should try to disable auto power savings. If this fixes the issue but you prefer to use auto power savings, make sure to enable CEC on your TV.

If your streaming player still does not power on, then the problem may be with the power adaptor. If your streaming player is under warranty, contact Roku Customer Support to return your player and power adaptor and get a replacement.

If the warranty has expired, a new power adaptor can be purchased from the Roku accessories store.
