Ultimate Buying Guide for the Best Cox Cable Modem Router

Cox cable could easily be regarded as one of the largest ISPs on the US market today. Over the years, its subscriber base has grown, and Cox offers the best high-speed internet service to at least 7 million households throughout the country. What this means is that if you are looking for an internet service provider that promises the highest possible internet speeds, Cox is a company that’s right up your ally.

Now that you know why Cox would make a good internet service partner, let’s take a look at the most important component of this ISP service, the cable modem router that you should buy.

While there are numerous options on the market for you today, the truth is that no two cable modem routers are made the same way, which means that you must be careful about the features of the mesh system you are buying.

For starters, you need to know that unlike other service providers, Cox doesn’t use just any modem router. You must look for a Cox-supported modem. These modem/routers feature DOCSIS 3.0 or DOCSIS 3.1, and they are the only ones compatible with Cox. But that is not all – all Cox WiFi hardware must meet specific requirements; for example, the equipment must be run on the 802.11ac standard. And if you choose the Ultimate or Gigablast service bundles, which are advanced Cox plans, the equipment you buy can only have a minimum of DOCSIS 3.1 standard.

Below, we’ll take a deeper dive into the factors that you must keep under consideration for the best modem router for Cox. But first, a look at the reasons why you must invest in a Cox-compatible modem router.

Reasons for Cox-Compatible Modem Routers

  • Prevention of Latency – incompatible Cox hardware cause poor-quality network coverage, less than optimum routing, low modem memory, and it also reduced the distance between the receiver device and the transmitting device. So, low network latency, get a modem router that’s Cox-compatible.
  • Speed issues – Internet speeds will drop real quick if you don’t have Cox-compatible equipment. To enjoy high internet speeds of at least 100Mbps, the modem selected must be a DOCSIS 3.0 or higher.
  • You also need a compatible modem for advanced connectivity if you need extra ports, points, and lines. Finally, it’s getting the right modem is cost-effective in the long run.

Choosing a Cox Cable Modem Router

DOCSIS Standards

Wondering what determines the maximum speed of your modem? Well, the answer is DOCSIS.

DOCSIS refers to Data Over Cable Service Interface Specification, and each DOCSIS standard increases the speed at which information travels from your ISP to your home network and back.

The most common DOCSIS standard is DOCSIS 3.0, and it is designed such that it allows a maximum of 32 download channels all running at once (32×8 channels). The download speeds on this DOCSIS 3.0 standard is over IGb at 1216Mbps, also called Gigabit internet/

The next DOCSIS standard is DOCSIS 3.1, which is the latest standard. DOCSIS 3.1 is recommended for high speeds up to 10Gbps on download speeds and 1Gbps for the upload speeds.

So, if you are looking for the highest internet speeds, this could be a good option for you – depending on where you live. DOCSIS 3.1 modems are future-proof, but they are expensive. DOCSIS 3.1 is backward compatible with the DOCSIS 3.0 modems.

In as much as DOCSIS 3.1 modems offer the highest speeds, you need to keep in the plan you’ve subscribed to. If you are on a slow internet plan, stick to a DOCSIS 3.0 modem with more downstream and downstream channels.

The DOCSIS 3.0 modems allow modems to combine multiple channels for data streaming, hence high download and upload speeds.

Channel Bonding

This is the other feature that you need to look out for when looking for the best Cox cable modem.

When it comes to modems, data flows between your ISP and your network system on channels and channel bonding is the technology that makes this possible. Channel bonding will combine multiple channels, allowing more information to pass through all at once.

Note that the channels refer to the number of channels for downloads vs. the ones for uploads. A 32×8 channel system, for example, has 32 download channels and eight upload streams. The download channels are always more than the upload channels because we download more information than we upload.

If you are looking for a Cox modem, keep in mind the maximum internet speeds offered on your plan. The 24×8 channel system will have high speeds of 300Mbps, while 32×8 channels correspond to 1Gbps max speeds.

When To Rent and When to Buy a Cox Modem

If you’ve rented the modem you are currently using; you need to check your monthly bill to determine how much you pay in rental fees. Cox, like other ISPs, will charge different fees, although bundling their services by buying a plan for TV, digital phone, and the internet gives you a free modem.

If there is a rental charge on the bill, buying a modem would save you some bucks at the end of the year. In the long run, buying your own modem is cheaper than renting.

Regarding the router in the modem/router combo, you need to make sure that it has the following features:

  • High WiFi speeds
  • Ethernet ports
  • Beamforming and other wireless technologies
  • Dual-band frequency setup
