My question i have connected my main deco directly to my modem with ethernet. Then i ran ethernet to a switch. can i run ethernet to a second Deco and still connect a 3rd or 4th or more Decos via Wifi or do they all have to be wired if the second one is? Will this affect performance? I have ethernet in the house but i have a detached garage that i need better signal in and i don't have a way to get ethernet there. The system worked great when i used it with my last ISP because it had more ethernet ports available but this modem only has one so i have to go from the Deco to a switch and where i want to put my second Deco is just out of range of the unit. it is strange now i only have 2 units connected the main one and the one all of the way out in the detached garage and it seems to work so far so not sure if i want to connect some with ethernet or just possibly repossition the units in the hose and possibly add a unit or two. Any thoughts?
