iPad Air 2 Wifi on 10.1.1, I had upgraded to 10.2 (downgraded since) and had the same issue on 10.2.
When the screen's off and I get an iMessage, sometimes it pops right up with a notifications, other times I don't get the message until I open up the home screen. It can be an hour later, I have it set to notify me 4 times about new messages, but it won't until I wake up the device. It's very sporadic so I can't pin it to anything. Also sometimes when the screens off and I try to bring SIRI up, I get an unable to connect to the internet message. Usually (almost always) if I press the home button a 2nd time it starts to work. The only thing I can come up with is it's something with my router. Everything else is working with it 100% though. So I'm not sure, and don't want to go buy a new router if it's not the problem. Any idea's what else it might be?
Routers set to WPA2 AES.
