Step 1: Preparation for Setup
Now before you start unhooking everything take just a second to identify what you have, and where you want to place the router. Your computer should either be connected directly to a Cable/DSL Modem, OR a switch which is plugged into the Modem. If your computer is plugged directly into the modem move to step 2, if not keep reading. If your switch is 5 ports or less you can remove it from the equation and just set it aside because the DIR-628 has 4 slots for hardwiring computers into the network. If you need more than those 4 slots just connect the router to the switch.
Step 2: Connecting the Router
Computers with switches of 5 ports or less – Completely remove old switch, and plug everything into the wireless router. Make note that the Ethernet cable coming directly from the cable/dsl modem must be pluged into the Ethernet slot on the router and not one of the switch ports.
Computers with pre-existing wireless routers – match port for port.
