@David-TP Thanks David. The switch model is: TP-Link 8 Port 10/100/1000Mbps LS1008G Just to be sure, I should connect the Deco's one to another with the ethernet cable? Roy

I installed a tp link >> deco m4 range extender in a private house. One is connected to the router directly, the other three are connected to a network cable that comes out of the to link switch in...
