Feel free to share this information with an IT or networking specialist.
Synapse is designed to operate in a secure/password protected 2.4 GHz connection that is not VLAN isolated or subnetted. Your network should operate at 70%+ signal strength on your SSID broadcast, which is considered industry standard.
Most routers will support a WPA-2 password encryption and have 2.4 GHz turned on as a default, which extends internet range and allows for more reliable connections. If you suspect yours may not be broadcasting, consult your router manufacturer or hardware manual for more information on how to turn it on.
All in one modems are not recommended.
NOTE: Synapse will not operate or onboard to hospitality/hotel or guest network configurations. Synapse will also not work on a 5G network.
