For the best performance, systems should be connected via a Gigabit wired connection. Wireless
should only be used if a wired connection isn't possible or cost effective.
You should record the brand name and model number of the network adapters you are using, as well
as the driver version or source. Use Table 17.11 in the section, “ Configuring Your Network
Software ,” later in this chapter, as a template for storing this information.

Installing the Network Adapter
When installing an internal network card, follow this procedure:
1. Open the case and locate an open expansion slot that matches the type of NIC you purchased
(preferably PCI or PCI-Express).
2. Using a screwdriver, remove the screw securing the slot cover at the rear of the case.
3. Insert the card gently, ensuring that the edge connector is seated solidly in the slot.
4. Fasten down the card with the same screw that held the slot cover.
Tip
If you are a realist, like me, you might not want to close the case until you are certain the NIC
is working. (See the next section, “ Testing Your Network Adapters and Connections .”)
Once the network adapter is installed, you need to install the drivers for the card that match your OS.
Testing Your Network Adapters and Connections
Connect the network adapter to the network. With an Ethernet network using UTP cable, run the cable
from the card to the switch, turn on the computer and switch, and watch for signal lights to light up on
the NIC's back bracket (if so equipped) and on the switch. Switches normally use LEDs to indicate
the presence of a computer on a particular port, and they usually indicate the connected speed. If the
LEDs show that the card is connected at the correct speed, that usually indicates the card and
intervening cabling are functioning correctly. For other types of networks, see the diagnostics
provided with the network hardware for testing details.
Cables and Connections Between Computers
Depending on the network architecture you choose, you might need to run cables. If you are installing
a Fast or Gigabit Ethernet network (both of which use UTP cables), you need cables that are long
enough to reach comfortably between each computer's network port and the network's hub or switch.
