20 Best Cox Compatible Modems Compatible Modems in 2020

Are you a Cox subscriber who wants to get off the monthly equipment rental? It doesn’t matter whether you are on their fastest service plan or on slow speed plans, as our list includes the best-rated modems that are highly compatible.

The equipment rental might seem like a small amount BUT it is not!

Cable internet providers in the US charge anywhere between $15-25/month in the name of equipment rental. The modem rental you pay for 12 months can actually land a decent modem and use it without trouble for at least 4-5 years (unless you upgrade to a different plan/ISP.)

It’s not just Cox that charges you a hefty amount for renting a modem and router, but almost all the cable providers in the United States charge you a similar amount for renting equipment. And since, it can be avoided by purchasing a reliable modem, why not do it?

The equipment rental contributes to 15-20% of the revenue which is significant, that’s why your cable provider wouldn’t want you to purchase a modem/router. But since they can’t stop you directly, they do it by asking users to use the modems that are certified by them (although they have published their list on their websites.)

Best Cox Compatible Modems

These certified lists are quite long and are a bit confusing to most of the users. In my research, I found out that many people found modems on those lists, they were compatible with Cox as well. However, they didn’t provide adequate speeds according to the plan (although many modems are bad, but this can happen if you end up picking a modem that’s not suitable for your service package.)

The Buyer’s Guide

The Buyer’s Guide

Purchasing a modem could be a daunting task for most of us. As it not just involves checking the technical specifications, design, but it also involves checking compatibility with the cable internet provider & the subscribed service package. In this buyer’s guide, I’ll add a few things to consider when purchasing a modem.

1. Cox Compatible

Compatibility with Cox

Compatibility with Cox is one of the most important things to consider when getting a modem. If you end up buying an incompatible modem, then it won’t work or have trouble connecting/activating. That’s why it’s very important to make sure that the modem you’ve chosen is compatible with their service.

2. Compatibility with Service Package

Compatibility with Service Package

A lot of people end up purchasing cable modems that are not suitable for their service package. If you’re subscribed to a 1000 Mbps plan, make sure that your modem is at least capable of providing speeds upto 1500 Mbps (20% more than the offering is a rule I generally follow.)

In many cases, people subscribed to a service package of 1000 Mbps end up choosing a modem that provides exact 1000 Mbps speed or even less, in both cases the experience shall be bad. That’s why make sure that you are picking a modem that isn’t just approved with Cox, but is also suitable for your service plan.

3. DOCSIS Technology (DOCSIS 3.0 vs 3.1)

DOCSIS Technology (DOCSIS 3.0 vs 3.1)

Do you have a gigabit connection at your home? In that case you should be grateful to the revolutionary DOCSIS technology. It is due to this tech, that the coaxial cables that are used for cable TV are capable of providing gigabit speeds (which was previously only possible via fiber optic cable.)

Although most of the cable internet providers in the United States are currently using DOCSIS 3.0, a few of them have upgraded to DOCSIS 3.1. So when picking a modem, make sure that you get a DOCSIS 3.1 modem if your network provider uses that technology for their networking infrastructure.

4. Channel Bonding

Channel Bonding

Have you ever gone through a modem listing and found out numbers like 32×8, 24×8, 16×8, 8×4, 4×4? These numbers represent the downstream and upstream channels. So for a modem that comes with 32 x 8 channel bonding, it’ll have 32 channels for downstream and 8 channels for upstream.

Basically, when picking a modem, you should make sure that the channels on your cable modem are actually equal or above the below speed requirements.

  • 32×8 (DOCSIS 3.1) = High Gigabit Speeds (Between 1-10 Gbps)
  • 32×8 = Gigabit speeds (Between 1-2 Gbps)
  • 24×8 = High speed plans (Between 800 Mbps to 1 Gbps)
  • 16×8 = Medium speed plans (Between 500 Mbps to 700 Mbps)
  • 8×4 = Slow speed connections (Between 100-400 Mbps)
  • 4×4 = Suitable for very slow speeds (Between 5-50 Mbps)

5. Standalone Modem vs Modem/router combo

Standalone Modem vs Modem/router combo

If you are looking for the best performance or are on the highest service package of Cox then you should consider getting a standalone modem. Since it’s a standalone modem, you’ll also have to get a wireless router separately.

In case you’re low on budget or don’t need very high-performance and your goal is to save rent, then a modem/router combo would make sense. Since it has both the units built in, there’s a chance that the performance won’t be as good as the standalone equipment, but it should get your job done.

6. Bad Modems

Bad Modems

Yes, if you’ve gone through the official Cox compatible modems list, you must have noticed that it involves a lot of modems that come with the Intel Puma 6 and 7 chipset which are known for latency issues, security vulnerabilities, etc.

One way to avoid getting a bad modem is by picking the right modem from our website (because by default we avoid using such modems in our list.) However, you can also check out the list of bad quality modems (if you need a list of all the bad quality modems.)

7. Price

Price

Budget is one of the most important factors to consider when getting a modem. Like mentioned above, purchasing a modem actually helps you save the monthly equipment rental. You should decide a budget that you are willing to allocate for your networking setup and choose products accordingly.

I think most of the good quality modems cost anywhere between $150-250. In some cases they’re standalone devices, in many cases they’re a combination of modem and router.

The FAQs

1. Which is the best modem for Cox?

According to my research, is the best option in terms of both compatibility and high speed plans.

2. Should I continue renting or consider buying?

Well, purchasing a modem offers a better return on investment. The avg monthly equipment rental for most of the providers in the US is $15, 1 year usage shall cost $180 which is almost equivalent to the cost of a better modem and not to forget the ownership benefits.

3. Why should I purchase an approved or compatible modem?

It’s quite important to purchase an approved modem, because if it isn’t compatible with Cox, they won’t allow you to connect it. In case you still end up connecting, you’ll end up facing a lot of connectivity issues?

4. Is there any list of modems that I should avoid?

Yes, there are a few modems that come with the Intel Puma 6 and 7 chipset, they’re known to have security vulnerabilities, laggy speeds, and packet loss. You should avoid those bad modems.

5. Do I need DOCSIS 3.1 or would a DOCSIS 3.0 modem work?

This depends on the area and your cable provider. For instance, Comcast Xfinity has DOCSIS 3.1 in most of the locations in the US, however, the 3.1 technology isn’t implemented in all the locations. Also, if Cox supports the technology in your location, you should consider getting a 3.1 modem.

The Verdict

It doesn’t matter what your cable internet needs are. It also doesn’t matter which internet speed you’re subscribed to, if you’re in search of a highly compatible modem for your network, then this post should be really helpful.

In my opinion, you should consider getting a DOCSIS 3.1 modem with 32×8 channel bonding for gigabit connections and a future-proof setup.

In case you’re looking for a decent modem that can handle gigabit speeds (non DOCSIS 3.1) then you should consider getting a modem that has channel bonding above 24×8.

For medium intensive connection speeds, you should consider getting a modem that is compatible with Cox + has channel bonding above 16×8.

I hope that you’ve found the best cable modem for Cox. In case you have any trouble, feel free to contact me or comment below. I’m here to help.
