    Small But Powerful

    It gets the job done and saves me money in the long run because I don't have to rent my modem from RCN. You'll need a wireless router because it's not built in. I wish I knew that before I bought it because I wanted the two-in-one. However, I already owned a router so it wasn't a big deal.

    good peeformance and affordable cable modem

    it was pretty affordable (about $40) and no proble so far (for 2 weeks). it maximized my connection, and I just had to reboot it just once so far. I give two thumbs up for this item.

    So far, so good...goldilocks modem

    I got my bill from Spectrum and it was $20 more than last month's bill with no warning and no explanation. When I called Spectrum, part of their solution was for me to buy my own modem. I would save $10/month, the customer service rep said. After work I went to Walmart and they had three modems...I felt like was expensive with all the bells and whistles, one was cheap and super basic, and one was "just right." It seemed to get decent reviews and I was overwhelmed with reading modem reviews, so I bought it. I was able to set it up in around 10 minutes and most of that was waiting for Spectrum to activate the modem. I will update my review if anything changes.
    the small size and its speed and ease of setup

    Good product

    It worked great the minute I connected it. No problems at all.
    Works better for us than the high-priced router modem combo that the ISP installed


    Bought it in July of 2018. It stopped working at the beginning of September. Has Comcast Tech to come out to verify what was causing internet connection problems. It worked well until it suddenly died. I returned it and will order another and add a protection plan.


    Awesome little modem. I was able to call my internet provider and have it connected in 15 minutes ( that was my second try the first CSR wasn’t as knowledgeable as the second CSR) . However, I loved all its features. I can turn it off via an on/off button . I haven’t had any issues whatsoever. Great for the money - will recommend to anyone who wants to save some money in rental fees.

    Does Not Work with Suddenlink

    I purchased this Motorola MB7220 Cable Modem in April 2017. I have Suddenlink internet and had been using a Motorola cable modem for years with zero problems but wanted to upgrade to a faster internet with Suddenlink (50Mbps). The modem I had was still on the Docsis 2.0 with a 30Mbps limit and this new one is on Docsis 3.0 with a 343Mbps limit. However, after going through the setup, Suddenlink was able to activate the new modem with Serial & Mac but never found a connection to the modem and was never able to get an internet connection. I went through the entire setup process and the only thing that ever happened was the Welcome page from Suddenlink over and over. I tried going directly from modem to laptop via ethernet, I tried going from modem to router to laptop via ethernet as well as WiFi, still nothing. I went back to my old modem the same day and everything works perfect. Switched right back to this new modem and again, no connection! So the problem is definitely this new modem. Suddenlink rep over the phone was no help in resolving the issue, she just kept saying she can't even see a connection from their end. What a joke!

    So far so good...

    Doing exactly what we needed so far. Good price and quick service.
