Hello,

I'm not sure if router internet encryption is the right way to cut off internet connection to your computer. Generally, the only use for WEP is for keeping strangers from entering your network. XP tries to make it easier for you to connect, so it stores it automatically.

Something better to use is a program that cuts off the internet connection. One such program is the shareware program Internet Password Lock ($20). You'll probably find this much easier to use than a WEP key.

Hope this helps
