Okay Modem. Not much faster than my old one.
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.With my old modem, Netflix would buffer frequently. So, I upgraded to this one with the advice of Best Buy personnel. My cable company actually suggested a better, more expensive modem. But, Best Buy said this was the only one I needed. While the buffering has stopped, it has not improved my download speeds very much compared to my old modem. Overall, it is probably worth the price; but, I would be tempted to spend more for a better modem.
