How to Install a Network Connection Interface Card
A network interface card (NIC), also called an Ethernet adapter or network controller, is a computer hardware device that allows the computer to receive and send signals to other network devices such as external modems or routers. Most new PCs come with a NIC installed, but it is possible to install more than one NIC in a single PC. The process of installing a new NIC is similar to installing other PC expansion cards such as modems and sound cards.

Turn off the PC, unplug the cords and then open the case using a screwdriver. Typically, a medium-sized Phillips screwdriver can be used to take out a few screws along the right side of the back of the case to open it.

Locate an empty PCI slot on the motherboard. The PCI slots are located along the back of the case near the bottom of the computer. If your NIC uses PCI express, locate the appropriate PCI express slot on your motherboard. You can compare the gold-tipped connectors on the card to the size of the slots to find the appropriate slot to use.

Install the NIC. Position the NIC squarely in the slot and push it down firmly until the back of the card and the network port are flush with the back of the PC. You can put the screw from the slot cover back in to secure the card in place.
