Furthermore, if the affected device is either a Roku Express or Roku Premiere, please note that both devices are only compatible with wireless b/g/n networks on the 2.4 GHz spectrum. Ensure that your router is broadcasting a 2.4GHz Wi-Fi network for the device to connect to. You can check your device model by navigating to Settings > System > About.
You can also try configuring your router and use wireless channels 1, 6, or 11 which are the preferred channels in North America. Each time you change the wireless channel, you will likely need to apply/save changes before you are prompted to restart the router.
If your Roku device is able to detect your network based on the proximity of your wireless router, then it would appear to be an issue with your router. How old is your router? It's possible that the router may need to be replaced if it is outdated.
HELO HELLO, THE ROKU STOP FINDING NETWORKS, BOTH MINE AND ALL MY NEIGHBORS FROM ONE DAY TO THE OTHER. I CAN'T USE IT. IT ONLY DETECTS THE NETWORK AND CONNECTS IF THE ROUTES ARE CLOSE. HOW CAN I COLLECT TO INSTALL AN OLDER SOFTAWARE VERSION? I NEED TO USE IT, FOR THAT I BUY IT. THANK YOU!ANK YOU!
