Wifi Turns off


    Perhaps someone can help me.


    I have an LG K7 two weeks old. I prepay for my minutes and I don't have data.


    I will connect the phone to the wifi in my home. 15 minutes later, the phone will disconnect from the wifi. The wifi is very. Very. stable in my home. I have an ipod touch, kindle, and laptop that never fall off the network.


    last night, I was making a wifi call. 15 minutes into the call, the wifi disconnected.


    I have gone to:

    advanced wifi - keep wi-fi on when screen is off and have selected yes. The wifi still turns off


    How, Someone please tell me how to keep the wifi on.
