Getting a second router means there is a wifi network switch when the phone/device decides to switch network; I would go with a Ubnt/Mikrotik/TP-link solution rather than a second router if I must ...

I have bought into the Mikrotik system for couple years. Even setup couple friends' home with a mix of hAP and CAPs ... Those are CAP ac2. Hence I am asking here if I should look for alternatives.
