Once the main router is set up, please wait for approximately 15 minutes to allow it to optimize. During this time, you may see a message at the top indicating that the network is being optimized. Once that message disappears, proceed to power on the satellite.
Wait until the satellite flashes rapidly with alternating blue and white lights—this indicates that it is ready to pair. Then, check your Bluetooth settings for a device named 'Surfboard Onboarding'.
If all these steps are completed and the app still crashes when you try to add the satellite, please uninstall and reinstall the Surfboard Central app. You do not need to reset the main router again. After reinstalling, sign in using the same email address you used during the initial setup of the main router. The app should then take you directly to the home screen, as the router is already onboarded.
Also, please ensure that your mobile phone’s software is up to date. If there are any pending updates, please install them first and then try onboarding the satellite again.
Lastly, kindly confirm the version of the Surfboard Central app you have installed, as there are currently no updates available.
