Router setup help

You need to connect the cable that you used to connect to your PC, to the WAN port on the router (it might say internet). Then, you need to connect one of the computers to one of the LAN ports (might have numbers, so you connect it to 1). You then need to login to the router through your browser (generally the address is http://192.168.1.1/ but you should check the documentation) and ask your ISP for the PPPoE information so you can setup your router to dialup for you (otherwise you could use the dialer you've had on your PC, but that doesn't work as well because you might have to share the internet connection).
