Need help with Wifi behaviour

Hello everyone.

I need help with my customer's wifi network. He has 4 macbook pro and 4 wifi repeaters and 1 wifi router. All repeaters repeate wifi signal from the router to provide service to all of the house.

The problem is that the Macbook Pros disconnect between Repeaters and require manual action to reconnect. How to fix this?

The Wifi works perfectly with my Window's laptop.

 

I am a network installer, and this is the one wifi install i am having problems with.

Here is the layout of wifi -

The router connects to the ISP; ISP provides a dynamic IP.
Two repeaters connect wirelessly to the router. The remaining two repeaters connected to these two - one each.

The router is Linksys and the repeaters are TP-Link. All devices use the same SSID and the same security.

The problem we are facing currently is that when moving between two repeaters, the connection is lost and does not connect automatically. It requires either a manual reconnection on the macbook or the wifi needs to be turned off, then on and then the reconnection happens.
