I called Comcast to get an accurate download speed, but 3 techs and their manager could not verify my download speed. They kept trying to up-sell me to another package for an additional $10.00 a month. Which they would not be able to very either. The basic internet service does not support DOCSIS 3.0. Which is needed for video streaming without constant buffering. Roku, AppleTV, boxeebox, Chumby, Uebo, Bigstream all digital media receivers work best on the new Internet protocol. You have to pay more to get a modem that supports it. Even with that Comcast can't very the download speed. They misrepresent their download speeds. They claim to offer the fastest service in my area but they can't confirm it. All monopolies suck!!!
