Hello everyone,

 I wanted to configure the best internet possible using some Deco that were gifted by some friend. My network looks like this: the optical fiber enters the ISP's modem that has only one WAN port. Through this port an Archer AX53 gets connect using PPPoE and from Archer's WAN 1 the main Deco gets connected by a CAT5 cable. 

The Deco network is set as Acces Point and 2 more Deco satellites are connected to the main one. Now the problem is that the main Deco keeps disconnecting, after... lets say 30 seconds of running smoothly, the light turns yellow for 1 minute the red for a couple of seconds then back on white. After that the cicle begins again and again. 

All the Deco units and the Archer are up to date regarding the updates. If I plug in the cable from the Archer in my PC, I get no problems. When the Deco starts its cicle it appears as offline in the Tether app. The Deco network is set as Acces Point because it solved the problem in the first 2 hours of usage and I read only that is the way to set up a network interface like mine. 

What should I do? I am very frustrated at the moment. 

Thanks a lot.
