Help & troubleshooting for network issues, including connecting your device to your home Wi-Fi network, connecting to public networks, troubleshooting wireless issues & ethernet connections, and optimizing streaming performance.
On Tuesday, October 5th, I bought a Roku Express 4k from Walmart. I connected it to a TV and set it up with no problems. Wednesday, I turned it on and now it will not connect to the internet. It shows my wireless connection with excellent signal strength but will not connect to the internet. I have restarted the router several times and the Roku several times. I checked on the internet and this seems to be a common problem with the newer units. I have an older version of this unit on another TV and it works very well. All my other devices connect with no problem, but this new Roku will not connect. I started to return it to Walmart, but I would like to see if we can get it working first. I really like my other Roku and would like to get the new one going if possible. It worked fine the first day, next day no connection and nothing changed.
Furthermore, if the affected devices are Roku Express or Roku Premiere, please note that they 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 or underneath the player itself. 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.
