I have a house that has 16 rooms, approx 20,000 square feet, 2 floors, it has ethernet wired into 6 of the rooms. There is a main rack in the centre of the house on the ground floor with the broadband coming in through BT ADSL. The walls in the house are very thick.* I have already tried Devolo homeplugs and they are not working very good. So have decided wireless access points are the way to go. The router is a Netgear DGND3700 attached to a netgear 8 port gigabit switch. The 6 wired ethernet connections are going straight into the switch and into 6 of the rooms around the house. I would like to have a single wireless network covering the whole house and garden area.* Can i just install 6 airport extremes around the house wired into the ethernet connections that are already there and creating 1 ssid, using the same ssid for all access points with the same password? Also I was looking at using the netgear WNDRMAC routers as access points, but im not sure now. I would appreciate it if anyone has a better solution? I also have a single wireless printer that needs to be connected to the wireless access points. I have pc's, macs, iphones, ipads that need to be able to print from. Thanks Guys!
