Push notifications problems with wifi

[yagumoto]

Hi,

First of all, I'm from Spain, so sorry for my english.

Yesterday I bought an Xperia SP and I had problems with the push notifications in the next conditions.

If I am at home, and the mobile is connected to my wifi network, I receive push notifications without problems when I have the screen switched on. But if I switch off my screen, the wifi seems to turn off and I don't receive any push notification till I switch on the screen.

I have the STAMINA mode off and the Low battery mode off too.

How can I solve this problem?

PD: My wife has another Xperia SP and she has not this problem, so I would like to know if it could be a problem of my device.

Android version:
4.1.2
Compilation Number:
12.0.A.2.254

Thanks in advance

Thanks for your reply.

I had checked out the "Connection drops" section and all my settings were ok, so I decided to ask here.

I can navigate with wifi connection and I receive push notifications when I have the screen on, but when I lock the screen, if I send a mail to my mobile, or a whatsapp message, I don't receive a notification till I unlock the screen. In this moment, when I unlock the screen, the notifications appears inmediatly.

Thanks.
