Encryption A friend installed my router without encryption. How do I secure it?

To secure your belkin wireless network you need to type http://192.168.2.1 into your internet explorer or click on the link in this message.
On the left menu click on security,
Down the box choose 64 bit WEP OR 128 bit WEP.
Select Automatically generate hex pairs using Pass Phrass by placing a tick.
Type in a Pass Phrass in the box and click Apply Changes.
It will open a new window with encription key.
Write it down and keep it a good place.
Close your browser and you are done.
Click on your network icon to search for wireless, when found your network SSID, double click to connect and a pop up window will ask for the encription key.
Type in the key and confirm it and that's all the game.
Hope that help.
