Upgraded modem/router. IPhone stopped handing off calls to iPad
I reset the wifi network connection on both devices (iPhone & iPad). Wifi network is the same on both devices, and I’m signed into both with same Apple ID. Settings on both devices turned on to allow iPhone to hand off to iPad when both logged into the network. All other sharing across devices works fine (texts, photos, etc.). Have turned options on both devices off & back on again; rebooted both devices; turned both devices completely off then on again. Both devices indicate they are connected to wifi.
This feature worked fine until I needed to upgrade the modem and router, which entailed a new wifi network name and password. I’ve tried every suggestion I can find, but a few say (unhelpfully) that it might be a router setting, and a couple say I need to contact Apple support. I can’t find any details about what specific router setting might be the issue. I can’t find any relevant info on my ISP site (Spectrum) or forums.
Does anyone have suggestions?
