The modem that your internet service provider (ISP) gives you is usually decent, but not always great. Did you know that with some ISPs, you can actually use a third-party modem? Better yet, if your standard modem isn’t delivering the speeds you pay for, this can actually improve your experience.

Before We Begin
There are a few things you should know about modems before you actually spend any money. Below, we’ve listed some of the most important considerations to make.
Will a Different Modem Actually Help?
Modems aren’t magic. If you’ve signed up for 40Mbps broadband, the following modems won’t boost that any further unless you upgrade your package. Similarly, if you currently get 39.9Mbps, you probably won’t see an improvement when using a different modem.
You should also be aware that tech support teams are trained to diagnose problems with very specific hardware. Using a different modem could limit the amount of assistance from your ISP’s help desk if you run into problems.
What Else Do You Need?
A modem won’t get you online by itself. You’ll also need a router. It’s important to buy a router that can keep up with your modem, though. If you don’t, you won’t get the full benefit and in some cases, may actually find that your network speeds decrease.
If you live in a home with thick walls, you should also be aware that this could be the culprit behind poor internet speeds. Here’s a trick: try connecting your computer directly to the router using an Ethernet cable. Did your speeds increase? If so, there’s a chance that your current modem is working perfectly.
Best Budget Cox Modem
If you’re just looking for a way to boost network speeds or you’re not super-interested in the tech itself, you’ll probably be alright with an inexpensive Cox modem. The following section is dedicated to highlighting the modems that have the biggest impact on the lowest budget.
Let’s start by taking a look at the TP-Link TC-7610. This model costs less than 40 USD, yet it offers speeds of up to 343Mbps (42.8MBps). With upload speeds of up to 143Mbps, you’ll be able to push large files to the cloud in no time.
You’re not just limited to Cox, either. This product works with Xfinity and Spectrum too. We were huge fans of its simplistic interface; it’s not always easy to troubleshoot this kind of machine, but thanks to the TC-7610’s status LEDs, the problem is always simple to find. Good, right?
Well, it gets better. This modem is covered by a two-year warranty and comes with access to 24/7 tech support. One of the great things about this modem is its wide compatibility – it’ll work with all but the oldest routers, which keeps your overall costs as low as possible.
Ultimately, this is a modem best suited to people who just want to plug and play. While there are a few network security measures to configure, this is all done in the setup menu. Really, there’s very little to do but connect the cables.
Next, we have the ARRIS SURFboard SB6141. Like the previous model, this one offers 343Mbps downloads and has eight downstream, four upstream channels. However, the biggest difference is the number of supported providers: Cox is included, of course, but so are Comcast, Time Warner, Charter, and Cablevision.
The majority of the setup process is automated, making it easy to install even if you aren’t technologically inclined. Further, with a retail price of around 50 USD, it’s extremely affordable. You will have to purchase a router too, but that’s a topic for another article! Now, let’s talk aesthetics.
The SB6141 has a vented design. This means it’s less likely to overheat, even in hot conditions, which in turn leads to more reliable performance. There are five status LEDs on the front, and while it’s not always obvious what these mean, when combined with the modem’s documentation, you can diagnose network problems quite easily.
We liked that this model was so easy to install. As you can see in the image above, it’s as simple as plugging in the power, coaxial, and Ethernet cables. That’s already pretty great, but throw in a 90-day warranty, and the deal is sweetened considerably.
The last of our budget modem recommendations is the Motorola MB7220. It comes in either black or white and costs around 40 USD. That’s not bad considering modem rental often costs more than 100 USD each year! Okay, so how well does it perform?
In a word: admirably. This modem has eight downstream channels and four upstream, resulting in up to 343Mbps downloads. It comes with a quick start guide intended to get you up and running in a matter of minutes, and frankly, setup is so easy a child could do it.
The MB7220 comes backed by some of the best customer support around. There’s a dedicated, US-based phone number to call if you run into trouble, but you know what’s really great? The internal components are designed so as to be protected against power surges. Say goodbye to unexpected replacement costs!
With a two-year warranty, exceptional speeds, and a very low price point, the Motorola MB7220 is ideal for those buying their first modem. Of course, the fact that it’s so compact and looks great definitely doesn’t hurt.
Best Mid-Range Cox Modem
Want a modem capable of handling faster speeds? Well, these cost a little more. The investment is well worth it, however, especially if you share a house with several other people. The following models are capable of delivering speeds that make HD streaming on multiple devices as painless as possible.
The first is the TP-Link AC1750. The first thing you’ll notice about this modem is that it has double the download speed of our previous recommendations, at 686Mbps, or around 85MBps. That’s fast enough for three people to watch 4K video at the same time! So what else did we like?
Well, this is a hybrid modem and router. This means that once you buy it, you don’t have to spend another cent. When you consider routers cost at least 30 USD, this model’s price of around 65 USD seems more than reasonable. Let’s address the most important part, though: the setup.
As there’s more hardware to account for, the setup process does take slightly longer. However, it also simplifies things. There’s no need to configure a separate router and modem, after all. If you find yourself struggling, you can always make use of TP-Link’s 24/7 customer support team.
There really isn’t much more to say about this model. It’s a one-stop internet solution that comes with fast network speeds, a two-year warranty, and everything you need to get online as quickly as possible. If that’s not value, we don’t know what is.
Moving on, we have an even faster modem, the Linksys CM3024. This product seems to be one of the only modems whose status lights say what they mean in plain English, so bonus points to Linksys for that. More importantly, though, how well does it work?
With download speeds of up to 960Mbps (120MBps) and uploads of up to 240Mbps, this modem is perfect for those of us with extremely fast connections. It’ll be particularly useful for those who game or use peer-to-peer networks. That said, you don’t have to break the bank to get one as it retails for less than 60 USD.
This modem is completely plug and play. There’s no setup CD, no engineer installation, and no manual tweaks to make at all unless you want to. The only issue is that it heats up quite a bit, so make sure you don’t wedge it in amongst your other electronics.
There’s very little this modem can’t do. You’re not even locked into a Cox membership; all major ISPs are supported in case you want to change provider at some point. If you’re in the market for a fast, versatile modem, you could do a lot worse than this one.
Last but not least, we have the ARRIS SURFboard SB6183. This model is a little more expensive, at around 70 USD, but it offers increased speeds (up to 686Mbps download) and is compatible with all major US service providers. It’s also pretty straightforward to use, which is great.
You’ll notice this model features the same, standard design that all low/mid-range SURFboard modems do. That’s not necessarily a bad thing, though; it makes upgrading from one to another very simple. As ever, ARRIS offers advice on installation and a 24/7 tech support line buyers can call in case of problems.
There is a gigabyte Ethernet port on the rear of the unit that allows you to connect your computer directly. We’d advise against this for security reasons but it’ll provide ultra-fast internet access, at least in the short term. So who is this modem best suited to?
Simply, those looking for fast speeds, without the fuss. Because there’s no router built-in, this modem allows vast opportunities for customization. If that wasn’t enough to persuade you, it comes with a two-year warranty at no extra cost.
Best Premium Cox Modem
Let’s say you’re working with a slightly higher budget. Maybe you’ve decided not to settle for anything less than the best, and more power to you. Take a look at the modems below – they might be a little more expensive but you can be sure their performance speaks for itself.
We’ll kick this section off with the Motorola MB7420. It costs around 80 USD and supports works with six different ISPs including Cox. You will need a separate router but that’s okay; with speeds of up to 686Mbps, you’ll be able to stream HD video on multiple devices without any problems.
Okay, let’s talk design. The MB7420 isn’t anything special to look at, but its simple appearance makes diagnosing any issues very simple. You have your standard status LEDs on the front and heat vents on the side to allow the modem to remain cool even after extended periods of use. If you’re the kind of person that leaves electronics on permanently, this model is ideal.
Having trouble getting set up? No problem – Motorola offers several avenues of support, and there’s a reset button on the back in case you’re looking for a quick fix. There’s a two-year warranty included, power-surge circuitry, and a gigabit Ethernet port on the rear. So what are our final thoughts?
If you found the other modem’s support options lacking, the MB7420 would make a great choice. It’s simple enough to debug on your own but if you need help, it’s always available. Throw in fast speeds and it’s almost perfect.
The TP-LINK TC7650 is a cut above the other products we’ve covered. It boasts speeds almost twice as fast as the mid-range picks, at up to 1000Mbps. Believe it or not, there’s actually a few more advantages to choosing this product. So what are they?
How about a built-in dual-core processor? This helps keep things moving smoothly when you’re downloading large files. Still not sold? What about a two-year warranty period? Free, 24/7 tech support? A sleek, vented design? Okay, what if we told you it costs less than 90 USD?
There’s no need to worry about finding the perfect router, either, since the TC7650 is backward compatible with all 802.11 devices. Setup is simple enough; just plug the modem in. You might have to call your service provider, though, to allow them to finalize things on their end.
All things considered, this modem is best suited towards people looking for raw speed. If you’re into gaming or live with several people who all want to stream, this model would be great when paired with a suitably fast router.
The NETGEAR N300 is some serious tech. It’s not just a modem, not just a router, it’s a modem/router/network switch. Surprisingly, it isn’t as pricey as you might think – you can own one for less than 90 USD. Still, jack of all trades, master of none, right? How well does it hold up?
Let’s just say you’re not going to have any problems. You’ll see download speeds of up to 1000Mbps and there are plenty of different status LEDs to indicate where exactly a problem has occurred. There is one minor issue, though: this model only creates 2.4GHz networks, which are slightly slower than 5GHz but have greater coverage areas.
Worried about what your kids are doing online? This model provides access to an app that lets you block websites, even when you’re away from home. There are also more general content filtering settings to choose from, for a more hands-off approach.
This product is best-suited to people trying to tend to both their busy lifestyles and take care of their kids. It’s a reasonably affordable way to guarantee fast internet speeds, plus with the NETGEAR app, you have complete network control. Speedy AND secure? What more could you ask for?
Fastest Cox Modem
Maybe you’re more technologically inclined than most people. Maybe you just want to stream everything in the highest quality available. Either way, the following modems provide extremely fast network speeds and should handle anything you throw at them without any issues. Check them out!
First up is the NETGEAR CM700, a lightning-fast modem that costs less than 100 USD. This model has a unique, futuristic design that combines sharp angles and unusual shapes to create a modem that looks as great as it performs. Now, we said this product was fast, but how fast are we talking?
Well, with speeds of up to 1400Mbps (175MBps), it’s more than four times faster than our budget recommendations. If this modem came with a router built in, or phone line support, it would be perfect. Nevertheless, it’s a strong choice for anyone looking for total control of their network.
We say this because it can handle both 2.4GHz and 5GHz networks, and comes with built-in security options including a modem-level firewall, device whitelist, and port blocking. Want to limit the times when your kids can connect to the internet? Well, with this modem, you can!
Although this product is a bit more expensive than some of its rivals, we believe it’s worth the investment. Sure, cheaper modems might work in the short term but as internet speeds increase, you’ll need to upgrade. Why not buy a fast one now, knowing no replacement will be needed for years?
Finally, let’s examine the ARRIS SURFboard SB6190. This modem ditches the plain black design of its competition, instead fronting a clean white aesthetic that’ll look great in any modern office. At around 100 USD, this modem has to be exceptional for it to be worth the price – so is it?
It’s no slouch when it comes to speed, that’s for sure. With speeds of up to 1400Mbps, you can download a movie in as little as six seconds (assuming a 1GB file size). There’s no need to worry about wired speeds either, as this model features a gigabit Ethernet port at the rear.
Now, there are a couple of minor issues. First, there’s no router built in and no phone socket. Second, while you are covered by a two-year warranty, calls to tech support aren’t free. That said, if you’re buying a router like this, there’s a good chance you already know how to fix network problems, so this shouldn’t be a deal-breaker.
Realistically, this modem is overkill for most households. It’s more appropriate for people who want to tweak every aspect of their network or those who plan to use mostly wired connections. If that sounds like you, then this may be the best product available, period.
This section is dedicated to highlighting a product that will suit the majority of users. The modem market is saturated with low-cost offerings, but they’re not always worth their price. However, in this case, we found a real diamond in the rough – the NETGEAR CM400.
While this modem doesn’t have the fastest speeds, it provides speeds of up to 340Mbps. This is more than enough for watching HD video on multiple devices, and with a price of around 50 USD, it’s affordable on almost every budget.
Look at it this way: renting a modem can cost over 100 USD a year. If you can get the same speeds and save more than 50% of that money, isn’t that already a win? Plus, if you run into trouble with your ISP’s standard modem, they’ll likely just send another one out. In contrast, NETGEAR’s customer support team will walk you through the solution so you can take care of it on your own next time.
