Routers often host a lot of settings that you can work with to set up a network, but accessing them can be tricky if, for example, you've lost the tutorial CD. Fortunately, it's always possible to access a router's settings manually.
Look on the router's underside and/or manual to find the "admin address." This usually consists of an IP address that most commonly looks like this: 192.168.0.1
Open a Web browser on a computer connected to the router.
