I have a thought......
Are you restricting access to your router? This setting will only let certain MAC addresses attach. In theory only devices you specify should be able to use your network. (Of course the MAC could be spoofed...but that's a different story)
Log in to your router and check for an option like this.
I think on my netgear it's called setup access list. I can't remember specifically what it is called on other routers. But it's there. I always turn it on when I set one up for someone.
Check your router's manual about how to log on to change settings. It should be something like typing
192.168.0.1 in a web browser attached to the router with a lan cable.
usually the user is admin and the password is password.
I'm betting this is the problem.
I realize you say you are new to PPC's (I'm assuming computers in general) and I may have gone over your head a little. A little reading in your manual or online will help. I'll check beck to check up on you.
Hope this helps.
