Mirroring / casting no longer working

Jump to solution

Hello people

I've had a Roku Premiere for several years, which I use little, although I do occasionally use it to throw some pictures or Powerpoints onto the TVs (it's plugged into a 2-zone AV amp) from my phone or laptop.  I haven't done so for a while - and I now find it's not working. On my Android phone, the device often fails to show up in the list of available devices; when it does, much more often than not the connection fails (but not always - on the few occasions it's worked, it's entirely performant, once connected). On my Windows 11 PC, the list of available devices has only contained the Roku once - and it refused to connect. 

All the devices in the equation are on the same 192.168.0.xxx network.  In fact, they're all connected to the same WAP, which hangs off the router.

I have disabled all the firewalls that might block Miracast: no joy.
I have power-cycled my router and WAP, several times; no joy.
I have reset the network connection on the Roku: no joy
I have factory reset the Roku: no joy

It is more than irritating that it does, very occasionally, work from my phone.  I have not got it to work from my Windows 11 laptop since I discovered it had these recent issues.

What do I do next??

Hi @Jooeedee,

Welcome to the Roku Community!

Thanks for bringing to our attention that you are encountering difficulties using the Screen Mirroring feature on your Roku device. We appreciate your efforts and the troubleshooting steps you took to resolve the issue.

Here are a few things you can try to troubleshoot the issue:

  • Make sure your PC and Roku device are connected to the same network: Double-check that your computer and Roku device are connected to the same Wi-Fi network. If they are not, connect them to the same network and try mirroring again.
  • Check your firewall settings: Your computer's firewall may be blocking the connection between your laptop and the Roku device. Try temporarily disabling your firewall to see if this resolves the issue. If disabling the firewall allows the mirroring to work, you may need to adjust the firewall settings to allow the connection.
  • Check for Roku device updates: Make sure your Roku device is running the latest software version by going to Settings > System > System update > Check now. If an update is available, install it and try mirroring again.
  • Try restarting your devices: Restart both your PC and Roku device and try mirroring again.
  • Use a different mirroring method: If none of the above steps work, try using a different mirroring method. For example, you can use the Roku mobile app to cast media from your phone to the Roku device or try using a third-party screen mirroring app.

We hope you find this information useful. Feel free to let us know how it goes.

All the best,
Chel

I have a 32" Onn Roku tv and an Onn 7" tablet. I had the tablet set up to cast/mirror to the tv but now it will not. I did a factory reset on the tv, reset up everything, checked all settings on the tablet, but the Onn tv does not show up in the list on the tablet. I have 2 other different brand of tv's that do show up on the tablet but not the Onn tv. What now
