Chapter 2: Networking Basics
The Use of IP Addresses
Broadband Router
A DHCP server can either be a designated PC on the network or another network device, such as the Router. By
default, the Router’s Internet Connection Type is
Obtain an IP automatically
(DHCP).
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.
For DSL users, many ISPs may require you to log on with a user name and password to gain access to the
Internet. This is a dedicated, high-speed connection type called Point to Point Protocol over Ethernet (PPPoE).
PPPoE is similar to a dial-up connection, but PPPoE does not dial a phone number when establishing a
connection. It also will provide the Router with a dynamic IP address to establish a connection to the Internet.

The Back and Side Panels
The Router’s ports and Reset button are located on the back panel of the Router.
If the Router is having problems connecting to the Internet, press the Reset button for just a
second with a paper clip or a pencil tip. This is similar to pressing the Reset button on your PC to
reboot it.
If you are experiencing extreme problems with the Router and have tried all other
troubleshooting measures, press and hold in the Reset button for 30 seconds. This will restore
the factory defaults and clear all of the Router’s settings, such as port forwarding or a new
password.
