ESP32 with Tp-link Deco m4

[IbrahimMuala]

Hello,

ESP32 board: DOIT ESP32 DEVKIT V1.
Router and Access points: Deco M4 V2 (3-pack)

I have bought a Deco M4 V2 (3-pack). I used one as a router and the second and third one as access points. I successfully made the ESP32 connected to it. but I found that ESP32 connected to the closest deco and it stayed connected to it, even if I walked and went to another deco.

Why it doesn't get the WIFI signal from the closest ones?
