A Review and Comparison of The Top Modems For COX You Can Buy in 2019

  Last Updated:

Choosing the best modem for Cox is one of the integral parts of your home network. Connect the wrong one, and your speeds might be greatly hampered.

Cox, like many other internet service providers, includes a device as part of the subscription package to save you the trouble of having to purchase one yourself.

However, that convenience doesn’t come free of charge and Cox charges a monthly fee for as long as you use the modem. Although the charges may seem minimal compared to the cost of a new device, over time they can really add up.

Buy your own, though, and you'll have paid off the cost of that device in rental fee savings in less than a year. Although Cox offers quality and good internet speeds, the cable modem that you use can greatly affect your experience.

Choosing The Best Cable Modem

There are a great array of modems on the market today. However, before you go out and purchase one, you should first ensure that the device is compatible with Cox.

Premier and Ultimate package customers are required to have DOCSIS 3.0 capable devices with 8 x 4 or higher channel bonding so the package speeds can be achieved.

There are still a few DOCSIS 2.0 devices that are compatible with Cox network but if you want to subscribe to Preferred, Premier, or Ultimate packages, Cox recommends you to upgrade to a DOCSIS 3.0 capable device.
