The traditional method of connecting desktop computers to a network is to connect it to the modem via the Local Area Network (LAN) ports located on the back of the wireless router. This allows you to take advantage of a consistent Internet connection and frees up room on the wireless portion of your network for laptops and other wireless networks. Adversely, laptops are traditionally connected to the Internet through the Wi-Fi antennas located on the wireless router. This allows the laptop users on your network the ability to roam freely.
Things you need
1 Plug an Ethernet cable into the Ethernet port located on the back of the modem. Usually, the port is labelled, "To Computer" or simply, "Ethernet." Push the jack into the port until it clicks in place.
2 Plug the other end of the Ethernet cable into the Wide Area Network (WAN) port located on the back of the wireless router. Routers only have one WAN port and usually the port is segregated from the other Ethernet ports on the router. In some cases, the port is labelled, "To Modem" or "Ethernet."
3 Turn the wireless router on. Routers such as D-Link, Linksys and Belkin do not have a power switch. To turn them on, plug them in. Some lesser known models may have a power switch.
1 Plug an Ethernet cable into LAN port 1 (LAN1). Push the jack into the port until it clicks onto place. Routers have lights located on the front that light up when Internet is successfully pushed through the access point. In this case, the access point is LAN1. Inspect the lights on the front of the router to ensure LAN1 is lit up.
2 Plug the other end of the router into the Network Identification Card (NIC) located on the back of the computer. Usually, the Ethernet port is titled, "Ethernet" or "To Modem."
3 Turn the computer on and allow it to boot up. With the computer connected to the LAN directly, it always has Internet connection. Once booted, open a web browser to surf the Internet.
1 Enable "wireless" connection on the laptop by accessing the wireless network manager. To do so, double-click on the wireless signal icon located on the tool tray on the bottom right corner of the computer screen.
2 Select "Wi-Fi ON" from the drop-down menu located on the lower left of the wireless network manager. The computer locates all open and secured networks within range of the computer.
3 Select your network from the list and check the box next to "Save Network." Checking the box allows the computer to reconnect to your network on its own in the event it loses connection.
4 Click on "Connect" to establish a network connection. Wait until you get a pop-up box indicating that the computer is connected and ready to use before you launch a web browser.
