Cable/DSL ISP Settings
To use the xDSL/Cable ISP settings, you must configure the router. ISP use
either static or dynamic IP addresses. Check with your ISP if you are not
certain which one it uses. If your ISP uses a static IP address, it means that
the IP address of your router is always the same. Most ISPs use dynamic IP
addresses. They assign you a new IP address every time you connect to the
Internet.
If you have a static IP address, do the following:
Enter the IP address that your ISP provided.
Enter the IP subnet mask.
Enter the ISP gateway address.
Enter the DNS IP address.
