    • great modem!

      Needed to replace my aging Motorola surfboard modem, and wanted to replace it with a product I know to be reliable. This modem was so easy to install, and a very good value. I'm very happy with this modem and would recommend it to anyone.

    • I thought what I had was fast...this is SUPER fast

      My modem I was renting from the cable company at $60/year at 10 years I thought was OK at 36 Mbps as far as speed, but today with more WiFi devices in your home this 160 Mbps is super FAST. The router lets you know when it is operating in Ethernet or Fast Ethernet mode OR in high-speed Gigabit Ethernet mode. I have seen a HUGE difference in speed alone uploading my data into the cloud.

    • Does what it is suppose to do....

      I'm using the Motorola SURFboard SB6121 Cable Modem instead of renting a cable modem from Comcast (yes, this is an Comcast approved modem). My speeds from Comcast are the same if not a little better with this modem.

    • Stopped paying for rental modem

      At a lower price than retail, this has turned out to be a great buy. I think the data transfer is quicker than the rental unit. A wireless router needs to be purchased separately. This is an approved device for Time Warner Cable.

    • Comcast compatible

      What can I say? Easy to install, took just a few minutes on the phone with Comcast to get it activated and saves me rental fees. I'm happy.
