Most, if not all, wireless routers can be set up without the software they come with. Here are the step by step instructions for most D-Link Wireless routers, but more specifically the DIR-628.
Step 1: Preparation for Setup
Assuming you just purchased the router, open the package and remove the Wireless Router, A/C Adapter, and the Ethernet Cable. You can leave the CD inside the packaging, you won’t be needing that.
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.
