I'm located in Oregon. But that is exactly what I purchased this modem to do. Unplugged the comcast modem, replaced it with this modem, called comcast gave a representative the MAC address from the label on the modem, and returned the old one. Now no more $7 lease fee. Hope this helps.

If you receive internet service through AT&T DSL, then this will NOT work for you. Cable Modems are used for cable TV type providers. You're looking for a "DSL Modem".

No, the USB port on the back of the modem is a type-B connector and the connector on the Magic Jack controller is a type-A. They are made this way to prohibit backwards communications.

The USB is actially an output similar to the ethernet output. I think some laptops allow you to connect to the modem via USB instead of ethernet port. In that case, you can use this USB port.

This unit is a "cable" modem, and you need a cable service provider in order for it to work.

If you don't want to own a cable modem, you can rent a unit from your service provider, for a nominal monthly charge.

As of today's(Oct 24th) local office visit, for Comcast "extended" basic 80(+/-) TV channels and Internet bundle(my choice), this version 2.0 modem is good to go! Best guess is there are several modems depending on your application. It appears to be a matter of how you will use it. It also appears to be more complicated than it needs to be; as it changes from region to region. Best regards!

Visit Comcast's DOCSIS Devices page for list of approved modems.
The only DOCSIS 3.0 Motorola modems listed are: SB 6120; SB 6121 and SBG 6580(modem gateway). Those available at W-M are higher cost than the SB 5101U.
Regret this answer is so dated - just getting around to my own "research".
