@Solla-topee Hello,

Thanks for the reply.

Regarding the questions you did:

1 - See the attached pictures

2 - All cameras and IoT devices are configured to get the IP Address over DHCP

3 - Yes

4 - Yes MAC address is always the same. That´s the reason why I'm not getting why Deco DHCP is assigning other address.

As you can see in the images I would expect a camera with MAC 6A-FF-7A-B8-4C would have the IP address 192.168.68.203.

It was assigned with IP address 192.168.68.89.

  @David-TP I assigned the MAC address manual and reboot the system and everything is working now.

Thanks for your support.

@David-TP The problem is back, but this time I know what is going on with it.

So I have a Deco x50 system and also a RE365 working as an extender so the camera I referred to in my previous posts could get a stronger signal.

From the link I am sending below, I have an idea of what is causing this issue:

https://community.tp-link.com/en/home/forum/topic/235352?replyId=626878

So the RE365 extender is using the MAC Address Proxy mode which is generating virtual MAC addresses.

I had this RE365 extender for a while and was basically the reason why I went for the Deco mesh system because I thought that being on the TP-Link environment everything would work with no issues.

How can I overcome this issue? Can I disable MAC address Proxy mode on the RE365 extender? How can I use address reservation on the Deco system when using a RE365 extender? Please don´t reply with the same solution I posted above because those are unacceptable... 

Regards
