Your message left it unclear as to what the problem is.
If you have cable/dsl at home, attach it to your network and update it.
If you have a problem getting it to recognize a network adapter that's one problem.
If you need a dialup account, there's really nothing to do other than get one.
My suggestion, maybe you can get a wireless adapter installed and with luck find an unsecured host nearby that he can get on.
When I try to set up the "Connect to the Internet" on the laptop, it states I need an account. How the heck can I download NetZero if I can't get the laptop online? LOL
