I've the same problem. What is "battery guru app", I can't find where is wifi time out settings? Some android 6 option? Or 3rd party software?
"I have FINALLY found a wifi keep alive app that works very well with Marshmallow:
Free: https://play.google.com/store/apps/d...fikeeper&hl=en"
doesn't work!
Still no solution? Does anyone know is it a Android 6 bug or something about hardware of different phones? It is really frustrating!!! After 2-3 mins wi-fi goes turn off...
