Disabling V.90  

                   The purpose of this site is to help you disable the V90 protocol in order to connect to the
         internet so that you may download the newest version of the V90 protocol. Most modems on the
         shelves and/ or preinstalled in most computers right now have old or half versions of V90 which
         are not compatible with today's V90 standard.
