We bought 5 differents WIFI routeur TL-MR6400 and we want 5 different configurations for each of these

but since one is online (and close)  , the second is getting the configuration of the first routeur (ssid , password , admin password ect ...) 

How to disable this sort of mesh configuration for all of those devices , we don't want them to share those setups , password , ssid ect .... ?

Thank you for your help in this case
