Motorola SB6120 SURFboard Cable Modem Review:


I just got a great deal one of these from
Amazon with FREE Super Saver Shipping and no sales tax. After it was installed, I was pleasingly surprised at the amazing performance boost in my COX Cable Internet speeds. The SB6120 is reasonably priced, easy to install, and it’s raw speed will blow you away.

If your existing Cable modem is more than a couple of years old, you are probably paying the cable Internet provider for more speed than your old modem can deliver. This new Next Generation DOCSIS® 3.0 technology lets you surf up to 4x faster than older DOCSIS® 2.0 broadband cable modems. If your modem is more than 5 years old and uses DOCSIS® 1. 1 or older technology, you should definitely upgrade to take advantage of the lightning-fast broadband speeds that the SB6120 can provide.

The Motorola SurfBoard eXtreme Cable Modem is capable of reaching data rates up to 150 Mbps. That makes gaming, shopping, downloading, working, high-quality voice and video conferencing, and peer-to-peer networking applications far more realistic, faster, and efficient than ever before. The SB6120 delivers your complete personal media experience, at lightning-fast broadband speed.
