Buying Guide for the Best Cable Modems for Cox
Cox is one of the leading cable service providers on the internet with a subscriber base of at least 6 million users. The company offers numerous broad service plans for its subscribers, and there is something for everyone, starting with the cheaper 10Mbps plans to the Gigabit plans (1Gbps). Unfortunately, all these plans come with a monthly fee, which is why the idea of owning your own modem is quite appealing because you won’t have to pay these charges anymore. Besides the monthly savings, investing in a Cox-compatible third-party modem often means that you get to enjoy the best network performance, even as you enjoy a lower demand for electricity. There is also the fact that repairing a Cox modem costs more than repairing a third-party modem.
Seeing all that is in store for you when you choose to buy a cable modem for Cox, you obviously want to find and buy the best Cox-compatible cable modem. To do that, there are features that you need to look out for/ consider, and we look at all these features below.
Things to look out for in Cox-compatible Cable Modems
For most of us, the price of the modem will be the first thing that we look out for, but it would be a good idea to take a step back and delve into all the features that the modem offers because you want to be sure that the selected modem offers the best value for money.
Here are the features that you must look out for:
Channel bonding is one of the most important features to consider and look out for in cable modems because it determines the download and the upload speeds you will enjoy from the modem. The bonded or aggregated channels work like the lanes on the highway, with highways with more lanes having the capacity for more cars, hence high-speed transportation and movement from one end to the other. This principle applies to the channels bonded together in the cable modems, and the modems with a large number of aggregated channels will offer high-speed downloads and uploads.
To understand the channel bonding statistics of your cable modem, it is important to note that different numbers are used to describe the downstream and the upstream channels. The downstream channels are shown by the first digits, while the second set of numbers describes the total number of upstream channels. The downstream channels are always more than the upstream channels, specifically because we download more content than we upload, and most of what we do on the internet requires high download speeds.
That said, the best of the Cox-compatible cable modems will feature a large number of downstream and upstream channels that ensure support for maximum speeds supported by Cox.
To choose a plan from Cox, you need to keep in mind that the 10Mbps, 50Mbps, and the 150Mbps plans all feature the 16×4 channel bonding and they run on the DOCSIS 3.0 protocol, and all the other high-speed plans with 32×4 channel bonding or higher will fall in Cox’s ultimate plan.
The other important consideration to keep in mind in your search for the best cable modem for Cox is the DOCSIS standard. This is something important to note because, for you to enjoy the gigabit speeds offered by Cox, you must have a DOCSIS 3.1 modem.
DOCSIS technology stands for Data Over Cable Service Interface Specification, and it refers to the specification or technology that allows you modem to effortlessly pass/ move information from and to your cable ISP to your devices.
That said, you also need to consider the compatibility of the cable modem with the service/ plan you are paying for. Basically, most of the DOCSIS 3.0 modems for Cox will work with the plans offered by this cable service provider. But if you are unsure, you might want to head over to Cox to review compatibility. The good news is that the modems reviewed above are all compatible with Cox.
Besides being careful not to waste your hard-earned money, you also need to check the warranty of your modem because buying a modem is an investment into an important part of your network infrastructure, and you want to know that the manufacturer will replace or fix the modem in case it stops working after some time. Keep in mind that the best modem is designed to last.
Besides buying a modem that is built to last, you also need to look at the design features incorporated into the modem and how they will help you enjoy the best level of connectivity/ network management. We are talking about important features such as the indicator lights – you need these indicator lights to be easy to spot, but not blinding or just too bright. You should also opt for the modem that is more compact and just the right size to fit the designated spot in your home, whether on the shelf or your working desk.
If you’ve subscribed to a plan capped at 300Mbps, a 16×8 channel bonded modem will work fine for you, but if you need higher speeds, you’d need a modem with more download channels.
How can I protect my Cox-compatible modem?
One of the best security solutions offered is the Cox Security Suite Plus, which is powered by McAfee, and it allows for the best protection for at least 5 devices. But you don’t have to subscribe to this service always because some of the third-party modems you are considering feature advanced security features that you will like.
What is an End of Life modem?
End of Life modem or modems that come with the End of Life designation refers to the modems that were at some/ one point recognized as service-compatible modems but are no longer regarded as the best or the most compatible, either because they are unstable on some networks, they are no longer supported by the manufacturer, have reached the end of production, or they use outdated technologies. While some sellers still sell some of the End of Life modems, you should avoid them.
What is an internet modem?
Internet modems are the modems that providers need to be able to receive internet service. These have the traditional cable wire connected to the modem (the cable goes into the house, and the internet signals them shared/ transmitted via a router wirelessly or via wired connections.
Cox-compatible cable modems offer the best way for you to enjoy cable internet access from Cable, and the cable modems above are some of the best options for you. Keep in mind that although the rental fees for cable modems appear low, these monthly charges add up so fast, and you’ll end up with a big bill year after year. To keep down costs and to enjoy the best internet performance, you might want to find a good cable modem. Opting for a cable modem based on the latest technological standards is also an advisable option, and you won’t have to worry about an upgrade after a year or two. The standalone cable modem also means that you will be able to upgrade your router easily, should the need arise in the future, and it will cost less than replacing both the router and modem in the case of combined router-modem units.
