Please try the following:
• Check your speaker and mobile/controlling device are connected to the same network.
• If your router supports both 2.4 GHz and 5 GHz, ensure both are connecting to the same band.
• Check to see if other devices can connect to the router.
• Move your DiscovR away from possible sources of interference (for example, microwaves, TV sets or cordless phones)
• Reset the router.
Note: Depending on the mobile device you are using, some may require location settings to be enabled. If the above steps do not resolve this, please enable this before restarting the Wi-Fi setup process.
