If you own more than one computer or a device such as an electronic reader, video game system or smart phone, that is able to connect to the Internet, you may have a need for a wireless network. Your current cable Internet connection is ideal for sharing among multiple users or devices simultaneously, and you can purchase a wireless router from electronics or big box retailers to create your network. Installation takes just a few minutes, and enables you to enjoy the Internet from any room in the house.
Unplug your cable modem if it is currently connected.
Disconnect the Ethernet cable connecting your modem to your computer by pressing the tab on the plug and pulling it out of your computer's Ethernet port. Connect this plug into the "Line In" or "Internet" port on the back of your wireless router.
Reconnect your modem's power cord and, if applicable, press the power button. Your router's lights indicate when connectivity has been established.
Plug the power adapter of your wireless router into the router and into an available electrical outlet, and press the power button or switch to turn on the device. Once it communicates with your modem, it begins broadcasting a signal.
Install any software that came with your router onto your computer. You can temporarily connect a computer to the wireless router via an Ethernet cable to access the control panel, if necessary. If you router came with a default network name, or SSID, and password, you can instruct your wireless device to search for the network and enter the default password to continue. Otherwise, set up your wireless network's name and password before searching for the new network with your laptop or other device.
