Good modem

I was paying $10 per month rental for a modem. This allowed me to make a purchase to eliminate that monthly expense...

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 product

It worked great the minute I connected it. No problems at all.

So far so good...

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

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.

Wasn't what I needed, did not have a phone jack. To small.

needs to change category

this product comes up when looking for a modem with a router as "best seller", when it's just a modem... now i'm having to find a router to go with it.

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!
