Ultimate Guide To Replacing Your Cox Modem

Replacing Your Cox Modem

You’ll find that there are tons of modems and routers that are capable of Cox’s immense offerings. However, this doesn’t mean that all of them offer exactly what you need. It doesn’t even mean that the ones that do offer what you need will be the best the most efficient option. Regardless if you want to choose your own modem or do your own research, you have to start by knowing exactly what to look for and what to avoid. One of the very first things that you’ll need to know is that Cox is not currently compatible with any third-party voice modems.

If these services are something that you’re interested in, you’ll have to rent an EMTA from Cox. Besides this, there are a handful of other features and options that you need to consider.

Compatibility With Cox

This is something that has been stated time and time again, but it is worth noting just one more time. If the modem you choose is not supported by Cox, it won’t work. This doesn’t mean that they’ll only deny you customer support for technical issues and installation, but they won’t even be able to provide you Internet service.

This is because the software, hardware, and interface just simply won’t link up. To make sure the modem is compatible, you’ll need to check out the ISP’s official homepage or contact them directly.

Speed And Package Compatibility

Cox also offers a variety of service plans. In fact, they offer five. Your option will also have to be compatible with the package you choose or you’ll be wasting your money. For instance, if you have a 300 Mbps service package and want to receive 300 Mbps, you’ll need to choose a modem that offers 300 Mbps worth of speeds.

Unfortunately, if you have a package of 300 Mbps and buy a 1 Gigabit modem it does not mean that this will boost your speeds. The only way to get 1 Gigabit will be by upgrading your service package, which means paying more monthly.

Modem/Router Combo?

If you want wireless capabilities along with the perks of connecting multiple devices at one time, you’ll need to invest in a modem/router combo. This will provide you with lighting-fast wired Ethernet as well as convenient wireless Wi-Fi capabilities.

Ethernet Ports

Speaking of wired Ethernet, this is only possible through built-in Ethernet ports. Most modems do come with 1, but if you want to hook up multiple wired devices, you’ll need a modem with multiple ports.

For instance, if you want to wire in your TV, computer, and laptop, you’ll need at least 3 ports. Although you can always use the device via Wi-Fi, you won’t be able to achieve the speeds that you’d be able to achieve with wired Ethernet.

Signal Range

Just as speed and Ethernet ports are important, the range of the modem will be important as well. This is especially true if you are utilizing the wireless side and live in a larger home. Some modems are capable of providing as much as 1800 square feet of signal, while some can only provide 50 square feet.

Whatever the situation is, you’ll want to make sure the modem of your choice matches your needs. Modems with beamforming technology and range-boosting antennas will offer wider range coverage.


The Internet is a scary place when it comes to financial and personal information. Since your modem will constantly be sending and receiving information, it’ll be like a hub of information.

Someone can break in at any time. And, that task will be much easier with firewalls and encryption software. Make sure that the modem you choose offers top-notch security because the Internet is risky.


While everyone’s budget is going to vary, it will be possible to get a good modem at an affordable price. It’ll also be possible to get all the features you need. This will just take a little bit of time and research on your part, but with this guide, you shouldn’t have a problem.
