Motorola - MB7220 8x4 DOCSIS 3.0 Cable Modem 343 Mbps

I have XFINITY cable and wanted to use my own modem instead of renting. I found the Motorola both fast and easy to install, with the service I have, a call was needed to activate the modem along with the model number and serial number (on bottom), and a longer Ethernet cable (one that goes from the modem to the computer). The computer was lightning F A S T and works great. Never had any issue with it yet, works great, and no more rental fees. I then wanted to go wireless, so I also bought a BELKIN wireless router, and it also works great with the Motorola Modem. Now, I have 4 security cameras, 3 laptops, 1 desktop, 3 smart phones, and a notebook all hooked to this modem / router and still works great with XFINITY.

This is a magical device I spend for it only $30 and I save hundreds and hundreds of dollars from Xfinity I definitely recommend it for everyone

Only 2 mos. in service, performance has been flawless. A nice feature is the large size and color coding of the indicator lights/icons. I'm only paying Cox for 50 Mbs service (one 4k stream is ~15 Mbs.), so this DOCSIS 3.0 device serves my needs perfectly. If you need more than the ~150 Mbs max speed of this modem, or require DOCSIS 3.1, you'll need a more robust device, but for a basic cable modem, this is a good buy.

This modem stands out and has been doing a great job. It never failed and connection is really fast. Depending on the cable gauge I suggest to hang it somewhere or stick it with some adhesive. It is very lightweight.

Works great with Comcast n their security.. needed a service call for the security part of the deal n a follow phone call for lack of their skill set.. You'll notice the router bridged they added for the xfinity security in photo.

Like most things in this digital age Cable Modem's are very much an on/off sort of product. It either works, or it doesn't in other words. I'm quite happy with this motorola modem and happy to report that it works very well. Set up can't really be much simpler. Plug it in, attach your wireless router and then give your internet service provider a call so that the device can be registered to your account and within 15 minutes you're good to go. This particular modem is compliant with Time Warner/Spectrum which is who I currently utilize. This was a replacement for an Arris brand router that broke after 2 years unexpectedly. My previous Motorola brand router had lasted over a decade by comparison. Both brands fall under the same corporate umbrella, but given my own experiences I feel that the Motorola branding leads to more quality products, however your mileage may vary. This modem is not a top of the line modem, however for my modest 25mbps download/2mbps upload it is more than enough as it likely will be for most casual users. Rated at up to 300mbps, unless you have one of the ultra high speed 1gb/sec plans you will find it is more than sufficient for the average household. Best of all this modem rings in under $100 on average so it won't break the bank either. Easy recommendation from me.

I bought this modem to replace the one I was renting from my cable company. Why didn't I do this sooner??? It was so easy to set up... it was automatically recognized by my cable service. I am using it with the latest and greatest WiFi "router" - Eero

I wanted to reduce my monthly cable bill and I already owned a wireless router I liked. So I called Comcast and asked them about compatible cable modems. Of course, there are many to choose from, some even having the XFinity name brand right on the box. This modem was the cheapest in terms of what was on that list. I figured "why not" and bought it. I came home, plugged it in, and plugged in my wireless router. When I tried to connect to the internet, the XFinity login screen appeared, and all I had to do is enter my Xfinity login and password (the same one I use when paying my cable bill). The XFinity website then set up everything and it seemed to work fine. I did have some trouble with the website popping up again a few days later and re-configuring my modem. On a hunch, I configured my wireless router to clone the MAC address of the computer I used when logging into the XFinity website. Typically this is a setting that can be found on your wireless router's configuration page. Ever since then, the modem and router have been happily working together, and I haven't had to re-log in to XFinity. The performance is very good, as I regularly get 85MB/s download, which is the plan I signed up for from Comcast. I don't particularly like Comcast and probably will be upgrading to Google Fiber or AT&T fiber - both will be in my apartment building in Atlanta soon and I'll be looking at 1000MB/s rates when that happens. Until then, this cheap cable modem delivers on the goods at 85MB/s for a fraction of the cost of the other options. That's great in my book.
