DHCP (Dynamic Host Configuration Protocol) Servers

PCs and other network devices using dynamic IP addressing are assigned a new IP address by a DHCP server. The PC or network device obtaining an IP address is called the DHCP client. DHCP frees you from having to assign IP addresses manually every time a new user is added to your network.

A DHCP server can either be a designated PC on the network or another net- work device, such as the Router. By default, the Router’s DHCP Server func- tion is enabled.

If you already have a DHCP server running on your network, you must disable one of the two DHCP servers. If you run more than one DHCP server on your network, you will experience network errors, such as conflicting IP addresses. To disable DHCP on the Router, see the DHCP section in “Chapter 7: The Router’s Web-based Utility.”

Note: Even if you assign a static IP address to a PC, other PCs can still use DHCP’s dynamic IP addressing, as long as the static IP address is not within the DHCP range of the LAN IP Addresses.

If the dynamic IP addressing fails to provide a dynamic IP address, refer to “Appendix A: Troubleshooting.”

Router Setup Overview

This User Guide covers the steps for setting up a network with the Router. After going through “Chapter 2: Getting to Know the Dual-Band Wireless A+G Broadband Router,” most users will only need to use the following chapters:

•Chapter 3: Connect the Router

This chapter instructs you on how to connect a cable or DSL modem to the Router and connect your PC(s) to the Router.

•Chapter 4: Configure the PCs

This chapter instructs you on how to configure your PCs to be DHCP clients, if you have previously set static IP addresses on your PCs.

•Chapter 5: Setting up the Dual-Band Wireless A+G Broadband Router

This chapter will walk you through the Setup Wizard included on the Setup CD-ROM.

•Chapter 6: Configuring the Router’s Basic Settings with the Web-based Utility

While you should always use the Setup Wizard when setting up the Router, more advanced users may wish to do this through the Web-based Utility. This chapter shows you how to configure the Router’s basic settings this way.
