HI ctrimm15,
Welcome to Techimo!
I need to ask , Which OS are you using? Which version of IE? Do you know the brand of your cable modem(please post it here)? Is it ALL the time for every page or only on specific sites(some times a site will be unavailable due to technical problems, Etc...)??
Here is a terrific site to help you get started.
