Furthermore, if the affected device is 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.
Thanks for the help! I called my wifi people and had them make 2 separate Wi-Fi’s one for the 2.4G and one for the 5G. Thinking this would solve the problem, it doesn’t. I reset my Roku and my wifi and tried again still didn’t work the last option i can come to is to factory reset, but then if that won’t work what else can i do? I’ve never had a problem like this before.
