asterisk users - May 2005 - Configuring a Grandstream 486 Device with AOL Internet connection

I have road runner AOL broadband cable Internet at home and I am trying to 
configure a grandstream 486 ATA.  The problem is I don't get access to the 
Internet until I am logged into AOL.  Does anyone know how to configure an 
ATA device to use an AOL broadband connection that requires authentication 
before you can access the Internet?  I have tried talking to AOL, 
roadrunner and Grandstream and each one keeps referring me to the other.

Thanks
