How to deactivate dhcp from my "My Cloud Home DUO" nas?

I need to deativate DXHCP in order to give a fixed IP to my device, but i don’t find any tool to configure it


Thank you.

You are right. Maybe better to fix the ip address of the device in the router.
But, nevertheless, do you know if there’s a way of doing it in the My Cloud Home DUO directly?
Better still: the device has some web server that we can access to do some configuration?
I put the device address on my browser and received a json string:
{“key”:“notFound”,“message”:“Not Found”}
So there is a web server with a rest service on it, but i don’t know the methods i have to call.
