RT-AC51U Wifi Power Save Problem

[Acacio Capela]

Hello,

I am having a problem with my asus RT-AC51U. When my mobile devices went sleep mode the wifi connection is lost. On notebooks is even worst does not even need the notebook to go sleep mode to lose wifi connection.

I already test with other wifi and this problem does not occur.

Most common case scenario is:
Connect phone to wi-fi
Start using web.whatsapp on computer
Phone enter lock mode, screen off
After a few minutes(very random)
Webwhatsapp says phone is not connected anymore(webwhatsapp only work when phone is connected)

Then, I access my router page and my device does not appear on my client list.
If I unlock my phone, connection is resumed and it appears on client list. This behavior does not happen when I use other wifi(I tested it many times, to isolated my phone of being the problem)

My firmware is stock, last version: 3.0.0.4.380.8496
Model RT-AC51U
Stock wifi configuration, only tried to mess with wmm apsd to set it to disable, but it did nothing.

Does anyone ever had this problem? Know a way to fix it or some miracle configuration to disable wifi power save on routers?
