When two computers are in a network, they can connect to the Internet using the same Internet access. A computer network is a setup that connects two or more computers so they can communicate and share resources such as files, applications and devices. An Internet network requires a modem and a router.
Sign up for an account with an Internet Service Provider (ISP). You may sign up for DSL service with a telephone company or cable with a cable TV company. The company you subscribe to may send you a modem. If not, you must purchase one.
Plug the modem into a wall outlet. Plug one end of the phone line or cable into the modem and plug the other end into a phone or cable jack.
Plug one end of the Ethernet cable into the WAN (Wireless Area Network) port on the modem and plug the other end into the wireless router. Plug the wireless router into an outlet.
Restart both computers. On one computer, click Start and select "Control Panel." Click "Network and Internet," select "Network and sharing center" and choose "Set up a connection or network" from the left panel. Click "Connect to the Internet" and click the "Next" button. Select "Wireless" from the dialog box. This will connect this computer to the Internet through your wireless network. Repeat this step on the second computer.
