Im setting up a network at home Ill have 4 wired devices and I want wirless. acces all the fikes ill want to share will be stored on an external hard drive. Either via a nas drive or through the usb port on my router . My question is in what order would I write the hard drive the switch for hard wire and the router for wireless? I want my cable modem and switch down stairs and my router upstairs for signal reasons if some one could explain clearly or perhaps a map it would be greatly appreciated
