Motorola - 8 x 4 DOCSIS 3.0 Cable Modem - Gray

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.

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.

The SPECIFICATIONS section of the listing for this modem says it is 24x8. It is only 8x4. The PRODUCT FEATURES section is correct, but the SPECIFICATIONS section is wrong. So when COX showed up to install 300mbps speed Internet, they couldn't use it and had to install one of their own. Now I have to buy another modem, return this one to Best Buy, and return the Modem that Cox had to install. Thanks Best Buy for wasting hours of my time.

How this got this good of reviews is beyond me. Doesn't work as expected. Bands keep dropping out and now reset button doesn't work. One star is to many.

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.

For under $100, the modem is a great deal. Works just as good as the ones that you get from your cable company. I returned my modem back to time warner cable and now I'm saving about $130 a year on my cable bill. I haven't had any problems with the modem. Great product.
