A:Answer Hi, to your question, YES you can add a network switch. In my current setup, I have the 3 google wifi puck system, One in my computer room which is connected to a 5 port gigabyte Ethernet switch. One in my living room which is also connected to a 5 port gigabyte switch. and the other i just have directly hardwired to my android entertainment in my bedroom.
So for the Main Puck that is connected to the modem, that only leaves you 1 port. For the other 2 that are not directly connected to the modem, they have 2 Ethernet ports available (the modem port turns into a reg Ethernet port), since they are turned into bridges, so essentially if you wanted to, at the satellite mesh points, you can connect 2 Network switches on each of the ethernet ports on the puck and expand more.
hope that helps or makes sense
