This is how IP address reservation works on Deco: https://www.tp-link.com/en/support/faq/1795/

If you are trying to configure static IP addresses on devices itself, that will not work with Deco mesh.

  @Alexandre.  I just used that tutorial to configure it, and it still doesn't work.

Are you telling me that if I set static IP addresses on my computers, they won't work on the DECO router's network?

This is correct. It will be unsupported configuration.

Supported process:

1. Disable MAC randomization on device;

2. Configure device to request IP address dynamically;

3. Reserve IP address for that MAC in Deco app following the link I provided.

If that does not work, the process failed.

But, as a proof of process failure, you'll need to provide screenshots from your Deco app: device info page with its MAC and actual IP address Deco sees, IP reservation page in Deco app with that same MAC and IP address you configured there.

  @Alexandre. 

Okay, I'll send this information.

But that's not the only problem. It assigns those IP addresses to other devices that connect first, giving reserved IP addresses to devices that connect with MAC addresses other than the reserved ones.

I had already loaded all the MAC addresses on my machines, removing the random MAC addresses, as well as my phones and tablets. And yet, DHCP continues to malfunction; it doesn't respect the requirement to assign reserved IP addresses to other devices.

Something I don't understand: Are you telling me that if I set a fixed IP address on machines wired to a switch and the switch directly to the router, which means I don't need the decoder's mesh functionality, I still can't set fixed IP addresses so I can access them from outside through the router?

That is, no type of fixed IP address is allowed within a network managed by a DECO router, even if they're connected wired?

Configuring static IP address on device is unsuported in Deco mesh. If you configure static IP address on device, this is how it'll work:

1. Device will have its static IP address which will be ignored by Deco mesh;

2. You will not see device with static IP address in Deco app in the list of online devices: it'll be either shown offline or not present at all;

3. Because Deco will not respect static IP address configuration on device, it may allocate that same IP to a different device (or even to Satellite Deco), thus causing IP address conflict;

4. IP traffic routing to/from that device with static IP address will most likely still work, as long as there is no IP conflict.

DHCP address reservation is very basic functionality which leaves little for software developer error, if user follows the process.

One more thing. By default, Deco mesh allocates IP addresses in 192.168.68.* IP range. If you haven't changed that and you see dynamic IPs on devices from different range or subnet, you may be having another DHCP server active on your network.

Ok, How do i reserve ip addresses if the router not respect the MAC address reservation?

So far there is no proof it does not. 

Supported process for IP address reservation in Deco mesh:

1. Disable MAC randomization on device;

2. Configure device to request IP address dynamically;

3. Reserve IP address for that MAC in Deco app following the link I provided.
