Dynamic IP Addresses
A dynamic IP address is automatically assigned to a device on the network,
such as PCs and print servers. These IP addresses are called "dynamic"
because they are only temporarily assigned to the PC or device. After a certain
time period, they expire and may change. If a PC logs onto the network (or the
Internet) and its dynamic IP address has expired, the DHCP server will auto-
matically assign it a new dynamic IP address.
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 6: The
Router's Web-based Utility."
Router Setup Overview
Note: You should always run the Setup CD-ROM to configure the
Router for Internet access. If you wish to manually configure the
Router, you may follow the instructions in the Quick Installation guide
or this User Guide.
This User Guide covers the steps for setting up a network with the Router (see
Figure 1-1). After going through "Chapter 2: Getting to Know the Dual-Band
Wireless A/G Broadband Router," most users will only need to use the follow-
ing 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: Configure the Router's Basic Settings
This chapter explains how to configure the Router using your web browser
and the Router's web-based utility. You will configure the Router for Internet
access using the settings provided by your ISP.
When you're finished with these basic steps, you will be ready to connect to the
Internet. You can also modify the Router's settings further; for example, you
can adjust security features and other settings to enable online gaming (see
"Chapter 6: The Router's Web-based Utility").
