Do We Need A Special AT&T Configuratin For The Use Of ADSL?

As with any provider, you should have been given a CD or a sign-in name and password to go to the AT&T site to set up your account.  Your email address would be your sign-in probably.  When you have a provider you are given certain free-bees, such as a home page, email etc. And the provider's (AT&T) computer needs to recognize your computer on that network.

If you are having trouble connecting to AT&T, give them a call and someone can lead you through the configuration.
