Great Modem - Excellent Speed

I had a Motorola Surfboard 2.0 that was working perfectly, however, wanted a DOCSIS 3.0 upgrade to give me the peed I craved. This was mid-range in terms of cost, but from a great brand like Motorola. It's easy to setup, consistent in performance.

So far so good!

Easy set up, connected immediately and is much faster than the cable modem supplied by our cable company which I have since returned and am not billed for monthly any longer. Time will tell, however...

Pretty Strong Product

Bought it as a replacement for a much older modem. This one works amazingly and I could definitely feel a big difference, glad I asked support which model I could use and looked around for the best prices :)
