Step 1: Connect the Router
This step is straightforward??”disconnect the network cable from the broadband
modem. Connect the network cable to one of the four LAN ports on the back of the
router, shown in Figure 10-3.
Connect the power adapter and turn on the power to the router. It will take a
minute or two for the router to start up; meanwhile, turn on or restart your computer.
When the computer is ready to use, it will have established a connection with the
router and obtained an IP address. At this point you can configure your router for
your broadband connection.

Step 2: Check Your New Network Connection
The directions for your router should tell you the connection sequence and how to
determine that the connection with your computer is working correctly. We will verify
that it is working by checking for the IP address your computer should obtain from
the router. To do so, we will use the examples of both the Windows Status dialog box
for your network adapter and a DOS command under Windows??”IPCONFIG. Hopefully
you won??™t have to use IPCONFIG more than a few times, but if and when you
do, this small program can tell you a lot about the Ethernet TCP/IP connection.
The Windows IPCONFIG program is a powerful utility that can show you some very basic to
fairly detailed information about your computer??™s network connections - the most basic being
your computer??™s IP address and the IP address of the gateway leading from your network
to another network or the Internet.
