I have a Wireless Router (D-Link) in my living room and a repeater (TP-Link WA750RE) in my kitchen. Sometimes when I go to the kitchen and back into the living room, my Nexus 5 (Android version 4.4.3) doesn't switch to the D-Link router although it has a stronger signal. It stays connected to the TP-Link repeater instead.
When I switch wifi off and on again, it connects to D-Link Router, which provides much better speed. How can I force android always switch to the strongest signal? Is there a setting for it or an app?
