A WEP key is a security code used on a most WiFi networks. WEP keys allow a group of devices on a home network to exchange information with each other while hiding the contents from easy viewing by outsiders.
You have to enable WEP on your wireless router. And don’t forget to write down your WEP Key because some day you’re going to need to reset it on your PC.
You can also use MAC Address filtering feature of your router. This allows only designated devices to communicate with your internet access.
