Try these simple tips and troubleshooting steps as this may help with the connectivity issue: 1. Restart your router (even if other devices have no problem finding and connecting). 2. Restart the Roku to clear its memory via Settings > System > System restart (for a Roku TV it's Settings > System > Power > System restart) 3. Find and connect to your network via Settings> Network > Set up the connection If that doesn't fix it, try disconnecting the power to your Roku for a few seconds. When it comes back up, see if you then can set up the network connection.
