Cox might offer you the opportunity to rent a modem from them, but really, you should invest in your own modem.

You will need to buy a modem that is approved to work with Cox in order for it to provide you with an internet connection. While it might seem overwhelming, we have the information you need.

Benefits Of Owning A Cox Approved Modem

Cox Compatible Modems

​No More Rental Fees

Cox charges $6.99 a month to rent a modem with single band WiFi and $9.99 a month to rent a modem with dual band WiFi, which adds up to $83.88 a year for single band and $119.88 a year for dual band. Your own modem will pay for itself in no time, while delivering both 2.4GHz and 5GHz bands.

Better Performance

Getting a modem from Cox limits your choices as far as range and power capability. You need a modem that can handle the amount of streaming and the amount of devices that need a connection. Your own modem should be DOCSIS 3.0 or 3.1, offer more upstream and downstream channels of 24x8 or higher and more.

More Control & Better Security

Your own Cox compatible modem should have a firewall, or even a VPN that matches the protection that you want from your internet. The modem you get from Cox is not made for your individual network needs.

Modem Router Combo vs Separate Units For Cox

Once you decide to buy your own Cox approved modem, you will then need to decide whether you want a modem router combo or a separate modem. It is better to get a combo.

  • Combo units take up less space, making them easier to conceal.
  • Combos are less expensive. You will only be buying one unit rather than two.
  • Combos have an easier set up. You will only be setting up one unit instead of two separately.

How To Install A Cox Cable Modem (Router)

  • Plug your new modem into the power outlet.
  • Attach the coaxial cable to the cable wall jack with the other side attached to your modem.
  • Connect the Ethernet cord from your computer to the LAN port on your modem.
  • Open a browser on your computer and go to the address indicated in your modem’s instructions.
  • Follow the setup wizard or instructions provided by your modem.
