    Good Modem - 2nd Try

    Avoid paying carrier monthly rent on their box... This is a good cable modem but the 1st one I came home with did not work. Lights flashed and everything but no data. As usual, Best Buy exchanged easily and 2nd one works perfectly.

    My old modem worked fine, but was capped at 345 MPS so it was time to move up with the new speed package i was given. This thing is a lot faster at processing and i have noticed a faster response across the systems.
