I don’t want my kids accessing the INTERNET through my neighbors unsecured router.
I Do Not want to go and talk to my neighbor to lock his router up?

I want a solution where i can prevent my kids from changing the wireless network settings of the computers

both the computers are windows XP

You would have to do quite a few things to make this happen. The easiet would be to setup accounts for them that are locked down accounts. You would create an administrator account that gives you only access to the configurations of windows. From the administrative account, you can allow or deny them access to certain aspects of windows.

Here is a brief tutorial

The other option is to connect to your neighbors wireless, find his printer, and print out a note telling him he needs to lock down his wireless. I have done that before

well i’m planning to get a laptop soon. and i just wanna know what is the difference between all these? because i went onto staple’s (the store) website and saw these 3…so what is the difference?

Desktop – Top of the desk PC- The usual PCs with separate CPU, separate Monitor, etc.

Laptop – Top of the lap PC- Portable PC

Netbook – Book like PC- Basically a PC that is a smaller and less performing version of a laptop, also about the size of usual books.
