I have two wifi networks in my house. They are very far from each other.
When I go to the kitchen area I loose connection to my main one in my room and it connects to the second one.
When I go back to my room the kitchen one is still slightly available. But so slow I cannot load anything at all. My phone (Nexus 5x) however does not switch back to my main connection but just stays on this sluggish connection.
Anyway to force it to automatically choose the strongest available connection?
