    Bought it to replace the one from the cable company and right off I saw a greater CLEAR reception, computer loaded faster that I have ever seen it load. And buying it it saves me $91.00 a year rent, and like I said, it is a better modem! Semper Fi.

    Customer review by KRDJ

    5.0 stars by KRDJ

    When I learned I was paying Time Warner Cable $7 a month for a DOCSIS 2.0 modem (no longer in use) for many years and could purchase my own - I did. I followed the "where to plug in the three cables" instructions (cable company line, ethernet line to router and power line). With my computer and modem on, I called "TWC technical support" to give them the MAC ID number on the side of the unit. The TWC rep "set up" my new modem and removed the monthly charge. The entire process of hooking it up and finishing with TWC was less than ten minutes. I took longer to hide the new power cable behind my desk. Ordering online is a few bucks cheaper than purchasing in the store (and cheaper than Best Buy, Office Depot and Frys). My Walmart is a few blocks away so I had mine shipped to the store. They emailed me when the modem arrived. Walmart has a special line for "ship to store" pickups - so no waiting in the "merchandise returns" line. I will never pay a monthly modem fee again. So far, so good. Thank you Walmart.

    the modem works with comcast (although it took forever to initialize on their network, but that's one time only). it wil pay for itself in a year.

    • No. The coax is the cable your internet provider runs to you house.

    • The coaxial cable is the one that comes through the wall and provides your cable service. This modem has the jack to connect that cable.

    • You will need to purchase the coaxial cable seperatly. Measure the distance from hook up to you computer to make sure you buy a long enough cable.

    • According to the spec sheet there is an "F" connector which means yes, coaxial cable can be connected to this modem. This would be expected since this is a cable modem.
