the dsl speed is going to vary depending on your location to the CO. the further away you are ,the slower it gets. i think it's about 3 miles. they wont guarantee speeds for you. when i first got dsl about 6 years ago it was just barely faster than dial-up, but i had no other choice at the time. i think i was at the 3 mile (or whatever distance) limit.
