Windows 7 Internet Connecting

For about 1 week I was connecting to my internet running through my home computer and I know you can setup a new network using a home computer with a Local Internet Connection(so i did that) now I connected 2 of my laptops to that home computer and IT WAS WORKING JUST FINE. Now I turned off my home computer and turned it back on and it won't give me internet connection for my laptops. My home computer does work for the local area connection but not the internet connection I set up. HOW DO I get my laptops to connect back to this internet connection!?!? Thank you,
