I live in a house where each floor has its own router, basically two routers connected to one central router, acting as WAP with their own SSIDs. The issue I'm facing is the watch sometimes tells its connected to iPhone when I'm on terrace and at other times I get the "iPhone not connected" sign at pretty much the same place. I wonder whether the watch pulls known WiFi network information from the iPhone & thus can connect to a different network than the iPhone and still be able to communicate with each other? Or the watch can only work with the iPhone when both basically are on the exact same network? If the case appears to be latter then one way to get around the limitation would be to have all home networks to have the same SSID. Has someone tried this & did they get the desired result? And if someone has more information on the workings of Apple Watch with the iPhone over WiFi, then please do share!
