Guide to Setting Up a Wireless LAN

Get a wireless LAN router

The first step in your wireless networking setup is to purchase a router at your local computer store or from an online reseller.

I recommend: Visit CNET's product review site Networking section to find reviews on 802.11g routers. The editor's picks are a good place to start. A less expensive product with a slightly lower rating might serve your needs just as well as a more expensive unit with features you don't require. Visit price comparison sites such as BizRate or CNET's Shopper.com.

Set up your wireless router

The wireless router should come with step-by-step instructions to set up wireless networking that don't require reading the entire manual. Connect an Ethernet cable from the modem's port to the appropriate port on the wireless router. If the Wi-Fi router only has a single Ethernet port, then that is the port to use. However, if it has more than one Ethernet port, then the one to use to connect to the modem is often marked WAN (for Wide Area Network, meaning in this case, the connection to the Internet).

I recommend: If you have difficulties, visit the manufacturer's Web page (for example, Linksys or NetGear) to check for any wireless networking troubleshooting tips and ways to contact them.

Connect your notebook or desktop computer to your WLAN network

Most notebook computers come with built-in Wi-Fi support. You can also install a Wi-Fi card in a notebook or desktop computer if needed for wireless networking capabilities.

I recommend: The Wi-Fi setup guide on jiwire.com has helpful instructions for wi-fi configuration of different operating systems. If you need to add a Wi-Fi card to your computer, check with your computer manufacturer for recommendations of cards that are known to be compatible. Visit CNET's product review site for reviews on Wi-Fi cards.

Secure your wireless LAN network

Set up password security on your WLAN network. This will prevent unauthorized users from accessing your Internet connection and your private network. The exception would be if you are intentionally setting up a network for free public access (e.g., in a coffee shop).
