Hi,

The DHCP server is disabled when Deco works as AP mode, while when Deco is red, that means there is no internet access from main router,  the DHCP server will be turned on automatically and temporarily to issue IP address for the client device, so that the Deco unit can still be managed. 

That is why you get IP address assigned by Deco unit when the Deco unit becomes red and no internet access. 

It is suggested to check whether you can get internet from the internet box when the Deco becomes red. 

For the ARP -A command, you can refer to the below instruction, if it is not clear, you may search online.

And on your windows computer, you can press windows key + R key and enter CMD, then enter ARP -A to find the IP address and the related mac address.

Good day.

Hello!

 

If DECO is RED, WIFI is OK but in automatic adressing on the client, no access to internet, i can access to internet by doing in manual.

No DHCP activated on the switch.
