WAN Chapter 3: Connecting the Cable/DSL Wireless-Ready Router to Your Network Overview Unlike a simple hub or switch, the setup of the Cable/DSL Wireless-Ready Router consists of more than simply plugging everything together. Because the Router acts as a DHCP server, you will have to set some values within the Router, and also configure your networked PCs to accept the IP Addresses the Router chooses to assign them. You will need the following values from your ISP in order to install the Cable/DSL Wireless-Ready Router: · PPPoE with username and password (for some DSL users) · Your broadband-configured PC's static Internet IP Address (if applicable) · Your broadband-configured PC's Computer Name and Workgroup Name · Your Subnet Mask · Your Default Gateway · Your Primary DNS IP address If your broadband access installer did not leave you this information, call your ISP and they will be able to supply you with it. About Static & Dynamic IP Addresses About Static & Dynamic IP Addresses Static IP Addresses A static IP address is an IP address permanently assigned to a computer in a TCP/IP network. Static IP addresses are usually assigned to networked devices that are consistently accessed by multiple users, such as server PCs, or a print server. If you are using your Router to share your cable or DSL Internet connection, contact your ISP to see if they have assigned your home a static IP address. You will need that address during your Router's configuration. 6 7 Instant BroadbandTM Series Dynamic IP Addresses A dyn ...
