I've been having this problem for a few months now and I'm at the end of my rope. The issue is, after my iPad Air 2 (running iOS 8.4) goes to sleep, it will not receive any FaceTime calls. If I wake it, it will go back to receiving calls without any issues. At first I thought there was some iOS bug that disconnected the wifi after going to sleep but that can't be the problem since I continue to get emails and Facebook notifications. There's actually a YouTube video from a few years ago that explains it perfectly:
I'm currently living in Germany. My ISP is Vodafone xDSL running on an EasyBox 904 modem/router. For testing purposes, I have also used my Asus RT-AC87R running in AP mode but the result hasn't changed. After troubleshooting this for months, I decided the issue must be a hardware related problem with the iPad so I went back and exchanged with a brand new unit but unfortunately, the issue persists.
I would REALLY appreciate it if someone could help me solve this issue before I lose my mind.
Thanks very much in advance.
