Things You'll Need
Connect a Laptop to a Wireless Router Using a Windows Operating System
Purchase a wireless router that fits your needs and price range.
Follow the router's manual to set up the router and its Internet connection, which will probably require connecting a wired client to the router. Once the wireless router is set up, the wired connection is no longer necessary. However, it's best to leave the wired client connected if it's a separate computer from that on which you're going to set up WiFi. If something goes wrong, you can access the administration interface again.
Gather information from the setup process. In order to set up the wireless client, you will need to know the service set identifier (SSID),
the Wireless Encryption Protocol (WEP) key and the channel and mode.
Boot up the laptop and plug in the WiFi card. This will not be necessary if your laptop has an integrated WiFi card.
Install any drivers needed to use the WiFi card. Insert the disc that came with the WiFi card and follow the on-screen installation process. Most discs will trigger a new hardware wizard that makes installation extremely simple.
Double-click on the "WiFi Connection" icon. It can be found in the system tray at the bottom of the laptop screen.
Click on "Properties."
Select the "Wireless Networks" tab.
Use the "Add" button at the bottom of the dialog if your WiFi network isn't in the "Available Networks" section.Source: ehow.com
