I’m sure this is a very good product, but neither Motorola or Cox Phoenix are willing to help actually use the product, so unfortunately this review cannot be better.
The Issue – This modem is not supported by Cox (Phoenix Metro) as they do not believe it has even been launched yet. Having gone through several departments at Cox they were unable to initialize the modem for use with their service, as the modem is not on the master list in their system.
Motorola are unwilling to contact Cox in order to assist resolve the issue, so I am going to be forced to return this one to the store (Not Amazon) from which it was purchased.
Good luck with this and your service provider.

Well I bought this cable modem because other reviews give it 5 stars,but my cable company (a third world company)can not hook up this device in their network. So this is the end of my review.

Do not buy from Electronica Direct.
These people are not honest. I recently bought a Motorola SurfBoard Modem SB6120 from Electronica through Amazon.
It has stopped working within a week.
Electronica pocketed the money. Refuses to give a refund.

Not sure if it has increased my speed much, but it is working fine after having contacted Comcast to register the device on the network.
