I’m setting up IOT devices on my new Wireless Home Internet G4AR gateway. I’m trying to put the IOT devices on a SEPARATE network, as now recommended by all security wonks. But the “Add A Network” feature does not create a SEPARATE network, it simply creates a different SSID - all devices on all SSIDs can see all other devices on all other SSIDs.
How do I create a truly separate network? It seems inconceivable that TMob would release a new gateway without this basic security feature, even my 6 year old cheapo ATT gateway had it...
