Installing a Network Adapter

Installing any network adapter hardware involves two steps:

1. 
   Connecting the adapter hardware to the computer.
   
2. 
   Installing any required software associated with the adapter.
   

For PCI adapters, first power down the computer and unplug its power cord before proceeding with the installation. A PCI adapter is a card that fits into a long, narrow slot inside the computer. The computer's case must be opened and the card firmly inserted into this slot.

You can attach other types of network adapter devices while a computer is running normally. Modern computer operating systems automatically detect newly connected hardware and complete the basic software installation required.

Some network adapters, however, additionally require custom software installation. Such an adapter will often be accompanied by a CD-ROM containing the installation media or the web address you can use to download it free from the manufacturer's Web site.

Software installed with a network adapter includes a device driver that allows the operating system to communicate with the hardware. In addition you may also receive a software management utility that provides a user interface for advanced configuration and troubleshooting of the hardware. These utilities are most commonly associated with Wi-Fi wireless network adapters.

You can normally disable a network adapter through its software. Disabling an adapter provides a convenient alternative to installing and uninstalling it. Wireless network adapters are best disabled when not in use, for security reasons.
