Are there any recommendations when installing the Waybox within an underground garage?

Before installing the Waybox with an underground garage, we recommend:

For Waybox, check the Wi-Fi strength is adequate, at the installation location of the Waybox the Wi-Fi signal from your router should be higher than -70 dbm. 

If the WI-FI signal is not suitable, for example -72 dbm you may want to consider a Wi-Fi extender or a 4G/5G router. If choosing a 4G/5G router ensure from your garage a cellular signal is received, if not an external aerial can be added to this router.

For Waybox Pro Cellular, check the Cellular Signal is adequate, If not then an external antenna can be used. Please refer to the installation manual to learn how to install an external antenna.
