How old is your Pavilion? If it is like a Pentium 3 model or something, you may not have an internet card. If it is made in the last 5 years... there is like a 90% chance you've got one. Just call your local ISP... the phone company or the cable TV company. If you don't have a card inside, they will usually give you one for free as long as you keep the service for 6 months or more!
