    Netgear Modem

    This modem was easy to set up with Comcast on line. Just check the Comcast acceptable device page on their support page for the type of modem you need for the internet service you have with them. Ordered this modem thru EBay and picked up at my local Best Buy. Quick and easy.

    Not fast enough for Xfinity X1 Platform...

    This cable modem is okay for regular internet, from the participating cable provers but, not for the newer speeds of Xfinity X1 platform... My newly purchased unit would drop signal in a 2-bedroom condominium when, walking away from the G & N highspeed router I owned... So, I returned this Netgear CM400A for a Motorola/Arris SB6141B model problem solved... Since then, I have upgraded my highspeed router to a yes Netgear AC1200 WiFi 3.0 DOCS IS unit and now my speeds are faster than my cable provider's issued dual cable modem/router unit! Cha-ching will save a good $120.00 a year in South FL... Regards, Rubén G.

    Very simple, NO wifi functionalities

    In initially thought it has wifi functionalities, but it is so simple just one ethernet port!

    Works fine with Time Warner Cable

    I purchased this modem to avoid TWC's monthly modem fee. It was easy to setup (anyway, I am not a rookie) and works fine. I would only say that it heats up too much, though it never stopped working.

    Easy set up and great performer.

    What a gem. Price, value and performance was better than expected. So easy to set up--our cable provider made the transition tough as they were reluctant to lose their monthly rental fee from us. The modem will pay for itself in about 4 months....love it!
