With a Belkin wireless router you can connect computers to the same Internet connection without having to run cables between all of them. If you don't want any stranger with a laptop that is within the range of your wireless router to be able to access your network, you will first need to enable the router's security settings.
Power on any of the computers that are currently connected to a network through your Belkin wireless router. Click on the "Start" button and then open the Control Panel.

Scroll down through the Control Panel options and double-click the "Devices" icon. Right-click on the entry for your Belkin wireless router and click on "Update Driver." Wait for the latest software driver to finish downloading and then close the Devices window.
Open your Web browser. Enter the IP address for your router, which should be 192.168.2.1. Click on the "Login" button.
Leave the password text box blank and then click on the "Submit" button to access the settings menu. Click on the tab at the top of the screen labeled as "Wireless."
Find the "Security" link at the center of the page and click on it. Click on the "Security Mode" drop-down menu box and then change the security mode to whichever setting you want. Choose the "128 bit WEP" option from the drop-down menu if you want to enable security encryption on your wireless network.
Click on the "Generate" button at the bottom of the screen to generate the encryption key and then type in a password you want to use in the "Passphrase" text box. Leave the box empty if you want anyone within range to be able to access your wireless router. Click on the "Apply Changes" button to save the changes.
If you enter a password into the "Passphrase" text box, anyone who attempts to connect to a website by using your wireless router from any computer will be required to enter that password.
