@FUSCAO 

Hi, nice to see you again.

I see you also commented on the Samsung A53 with Deco X60 post and however I think these two issue are unrelated.

"Evertime i got away from the main Deco the wi-fi connection is lost, it doesnt connect to the other Decos", It seems like ZFold 4 does not support roaming between Decos.

When it is disconnected from main Deco, if turning off/on the wifi, will it be able to reconnect to Deco again?

I googled and found some users mentioned WIFI/WLAN Roaming scan on the software information page and maybe you could check whether you have this option:
