So here's the deal. My Xperia Z & my XB1 are the only things on the 5GHz band. Here is the problem; When I unlock my phone I experience a 3 minute delay before my phone actually processes data. I know its not the phone as my friends sky and fathers plusnet doesn't do this. - It also will not receive notifications when the phone is locked. Again it didn't do this on other ISPs just this one. - it had stopped for a while but after resetting the router it started up again.
Also this delay happens when you connect yo the WiFi for the first time. Any ideas would be great.
