are those two things one and the same? First off this is a wired network. I've got my cable modem receiving the internet. From there I go to a netgear RP614 router. From the router, I go to 2 desktops, 1 networked printer and my Vonage VoIP. All those things have taken up all Ethernet ports on the router. I need to add a second networked printer. So if I have this right, all I need to get is an Ethernet switch and plug it into my router and just like that I've more ports to expand. Kinda like a USB hub. ...is that right?
