I'm using some Asus router in range extender mode, i have to use it with same ssid as my main router, i have done all setup, but i'm still only using signal from my main router. I have used wifi analyzer app for android to check if there is two wifi signals with same ssid, and there is, but even if i get 30% signal from main router it doesn't change to the other router(that is in range extender mode) even if i'm standing right next to him. So do i have to completely be out of range for main router in order to connect to other one, or not?
