Your modem/router should have its own special website that lets you configure its options (I don't know about yours for sure, but most ADSL modems I use have their own websites for configuration). So you just need to find out what it's IP address is, and type that into Internet explorer.


Try this to find out the IP address:
Open up "Command Prompt" (Windows 2000/XP - Start->Run->CMD | Windows 9x - Start->Run->command)
In the new window, type in "ipconfig"

You should get a text like this:
Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.0.2
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.0.1
Use the ip address from the bolded line and type that into a URL in Internet Explorer: http://192.168.0.1

You should now be able to set up your router.
