Mapping Your Networking Infrastructure
|
479
When you have added the first connection to the Ethernet router, you must then
connect the cables to the network cards on your computers and devices. When you
have completed this task, you should see a green LED light up on each network card
and possibly see the amber activity light. If you see both of these signs, you have suc-
cessfully completed the physical connectivity portion of the networking process. If
you do not see both of these lights, it does not mean you have failed, as there may be
no data transmission on the line while you are connecting the cables.
If you want to connect more computers or devices than the ports on
the Ethernet router allow, you’ll need a hub or switch. With a hub or
switch, you connect a network cable between the hub/switch and the
Ethernet router. Then, instead of connecting the cables for computers
or devices directly to the Ethernet router, you connect the cables to the
hub or switch.
To finalize the router setup, you need to configure the network services available on
your router. Using the Dynamic Host Configuration Protocol (DHCP), you can
assign IP addresses to the computers and devices connected to your router. With the
help of your user manual, log on to the router and select the screen to configure
DHCP. You need to assign a network IP range for use on your network. If you have
only a small group of users, use the 192.168.0.1 range for use on your network, or a
similar network ID. Most routers have the functionality turned on automatically.
You may also need to input the DNS addresses of your ISP or the MAC address of a
network card.
To complete connectivity to the network, you must configure the network cards on
your computers and devices. See the “Configuring the IPv4 and IPv6 Protocols” sec-
tion, later in this chapter, for details.
Mapping Your Networking Infrastructure
Windows Vista provides a whole new way to navigate and manage the networking
features of your computer. For mapping your networking infrastructure, Windows
Vista provides the Network and Sharing Center, Network Map, Network Connec-
tions, and People Near Me. You can access and work with these utilities as dis-
cussed in the sections that follow.
Using the Network and Sharing Center
The Network and Sharing Center is a central console for managing your networking
experience. You can access the Network and Sharing Center by following these steps:
1. Click Start, and then click Control Panel.
2. In the Control Panel, click Network and Internet and then click Network and
Sharing Center.
