I am in need of some ethernet ports in my basement. Currently I have a Time Capsule on my 2nd floor as the primary router, with an Express on my 1st floor and an Express in my basement as extenders. I am considering replacing the 2 Express units with a single Extreme unit. The thought would be that the Extreme has gigabit Ethernet ports and would negate the need for a switch. It would also provide me with 1 extension to my WiFi network vs the current 2 extensions. I don't need the AirPlay features of the Expresses. Would the change to an Extreme be an overall positive to my network?
