Default WiFi Dropping

Sorry if i missed something , but on every kitkat ROM , wifi drops after sometime.
i am using connectify to create wifi hotspot & it gets disconnected if i don't use it for few mins even though hotspot is active.

I have to restart the hot spot in order to re-connect. & no this isn't problem with connectify because this problem doesn't happens in Stock ROM ,
Any solutions ?
