I do not have reliable mobile signal in my home. We recently upgraded the modem/router to the Xfinity xFi 7th generation from my own router. Since the upgrade, we constantly have calls dropped using WiFi calling on 3 different phones with both Verizon and AT&T, so it's clearly not a phone or mobile provider issue.
Are there any suggestions for settings updates or anything else I could do? Frustration is reaching an all time high when making phone calls. I would call support, but the calls drop!
