For any of our Deco products when a configuration is added to a node all nodes will create a link to each other.  This way if there is a break or issue in one link devices connected to that node will have another path to send their data down.  So yes all units communicate with each other. 

 How is this idea?

@Carl I've 4 m4 decos and all of them always show that they are connected to the main router. 
also, I've tried to reach dead spots by placing a deco satellite between the main station and another satellite but it doesn't seems to be working, the bridged satellite still tries to connect with the main station instead of the closer satellite and the link speed is really poor

Does x60 work different than m4?

My understanding is the technology is the same just that the hardware different.  While all devices are creating a star topology and connecting to each other we are getting reports like in this thread where they just use the direct connection.  My understanding is that this because the system believes that the direct connect is still the best route version a relays singal from one of the other satalites.  I'll go ahead and send this thread up to our Engieers for a higher review. 

I have an update from the system team.  

They confrimed what I have assumed.  While the Deco system does create a star topology it chooses the best or strongest source for connecting remote nodes.  However we have received much similar feedback and the R&D team is working on optimizing the networking mechanism. We have let the PM and RD engineers know the numerous feedback about this issue, and the optimization plan will be released as soon as possible.

+1 I am also seeing that every X60 connects to the main, regardless of distance.  And this is resulting in very poor coverage in some areas.  Hopefully there is some optimization coming to help this.

I have just purchase 3 deco m4 devices. Setup on the same subnet but different switches.

Initially when I setup the decos on the network they worked fine but now they can't see each other.

They all have ip addresses and I can access the Web page on each device.

I'm using the deco m4s in AP mode so they should communicate over a wired network and just offer WiFi in the black spots of the house.
