I have router Deco XE75 and a Synology DS718+

 

I activate DHCP on Synology (DSM 7.1)

The XE75 use Smart DHCP

 

Documentation specify:

"How does Smart DHCP work?

 

With the built-in smart DHCP, the TP-Link wireless device will send a DHCP server request when joining a network, and check if it can receive the response from a DHCP server.

 

If YES, the TP-Link device will think that the front device has a DHCP server enabled and that there is a DHCP server in the network, then it will turn off its own DHCP server. In this case, its clients will get IP addresses from the front device and can access the front device’s network."

 

I restart Synology, restart router XE75 but Smart DHCP not detect DHCP on Network.

 

note: 

   XE75 contain DHCP clients 

   Synology contain DHCP clients

 

Smart DHCP use XE75 DHCP clients

Et not Synology DHCP clients?

 

Thanks
