How to make iPhone automatically switch to the strongest wifi between router and Deco M4
I stay at a three stories house, first floor (ground floor) is using TP Link Router Archer C6, second and third floor are using Deco M4, each floor/ pcs. The problem is when I walk from second/ third floor to the first floor (ground floor), the wifi will stay connected to the Deco M4 instead of auto change me connect to the TP Link Router wifi. Same situation when I go up to second/ third floor, but the wifi still stay connected to the TP Link Router.
May I know anything I can do to my iPhone to change the wifi automatically?
P/s: TP Link Router wifi name and Deco M4 are different.
Is it if I make both wifi name same then it will switch to the strongest wifi automatically?
