    If you don't have a cable connection faster than 900 Mb you don't need a DOCSIS 3.1 modem and you'll likely not see a difference between 24 and 32 channels. This is definitely an excellent modem to go with until you do. I have two MB 7621s in different locations. Recommended.

    Decent reliable cable modem

    Bought this modem as it was highly rated from researching multiple sites. I also didn't want to pay a rental fee from the cable company. Reason for the 4 stars is every so often my internet stops working and I have to unplug/plug to reset then the internet works again. I have received a call from my cable company saying they're seeing a lot of ups/downs with the signal so maybe the issue is more on their end and not the modem itself.

    My existing modem began to get flaky. My ISP wanted me to rent a 3.1 or something higher from them. I checked their list and this modem was rated as doing just fine, thanks very much. And guess what -- it works just fine, thanks very much. No need to waste money with my ISP.

    Modem has been working perfectly for 4 weeks that I have had it. I replaced a 4 year old netgear 400 which kept losing wifi signal every day. With the motorola modem it has not dropped wifi connection yet.

    I moved from an apartment where I could plug my wireless router directly into an Ethernet port in the wall to a house that fed data via coax. This modem was the missing piece.

    I love this Modem. We upgraded to this modem because our old one was very slow and overheated. This new Motorola Modem is very sturdy and doesn't overheat like our old modem.
