Associate Sattelite of Kit #2 to Router of Kit ~1

Thank you very much for your response  BruceGuo 🙂

To be clear, my goal is 

- use K1 router, not to use K2 router (maybe I will keep it as backup)

- use K1 sat and K2 sat connected to K1 router

- All router and satellites are in the same network 192.168.5.x

- I want that new computers connected with Orbi Wifi or Ethernet of Orbi are in this same network 192.168.5.x

- I don't want router starts a dhcp server (and I hope it's not the default) because of conflicts with my actual dhcp server in AD.

- and obviously, I want that all orbi works in mesh mode with ethernet wired (space between two orbi is to big)

To make this I will

- I will switch my K1 router to Router mode (and check if dhcp server is desactivated)

- K1 router is connected to my network on the switch with Yellow plug

- K1 sat and K2 sat all connected to other switch on the same network (I have 6 switch connected with fiber)

- Add each sat (K1 or K2) with Sync Button

Is it ok like that ?

must I do something else to reach my goal ?

Thank you again
