If you are a Spectrum user, you will want to have the best modem for Spectrum possible.
Spectrum might tell you that this is the modem that is supplied by Spectrum, but the truth is, you will be better off buying your own modem.
Spectrum likes to advertise that they loan you a modem for free, but there are so many hidden fees in there that nothing is really for free. Instead, you will be stuck with a generic modem that will never be able to satisfy all of your network’s needs.
Save yourself the trouble and buy your own modem for Spectrum. This is what you need know.
Benefits Of Having Your Own Cable Modem For Spectrum
Save On Rental Fees
Compared to other ISPs, Spectrum’s rental fees for modems are cheap. In fact, they don’t charge for the use of their modem at all, but charge $5 a month to use the built-in router.
But, that adds up to $60 a year or $120 for two years and you still do not get to keep the modem. If you are paying for a device, you should be able to own it.
Any rental modem is going to be limited and not have all of the performance features that a modern user needs. If you would like to be able to heavily stream or game online, you will need the best modem for Spectrum that is capable of handling these features.
If you want the best performance possible, you should definitely buy your own modem instead of settling for the mediocre options that Spectrum will give you with their modem.
No two networks are identical and require different features to have the most efficiency possible.
A network that only browses online might be able to use the modem supplied by Spectrum, but if you want more security, better packet latency, and more choices, you will be much better off buying your own modem that meets your needs as well as your wants. A generic Spectrum modem will not be able to give you the right features.
The Difference Between Cable Modem vs. Modem Router Combo
If you are debating whether to get a modem or a modem/router combo unit, there are pros to both. There is not a right answer to which one is perfect for you, since it really is based on your needs on what you expect from your modem.
Pros For Separate Units:
- More customizable to your needs
- Update the firmware easier
- You don’t have to replace both units if one becomes obsolete
Pros For Combo Units:
- Easier to set up
- They take up less space
Likewise, there cons to both types of modems, which is why you need to think about which type is best for you.

If you are looking for a modem that comes with a built-in router for Spectrum, we suggest the Motorola MG7550. This is another homerun product from Motorola, bringing with it all of the reliability and power that you expect.

3. Netgear Nighthawk CM1200 Modem

4. Netgear CM500 Modem For Spectrum
Another good modem for Spectrum that works well if you are on a budget is the Netgear CM500. This cable modem is affordable, but that does not mean that it is not made of great quality or doesn’t have adequate speeds. It might not have bells and whistles, but this modem does its job well.
The CM500 modem is a tower design with a base that looks like two feet. This gives it more support to stand up than a lot of other modems. It also will have a longer lifespan than modems that are horizontal as it is able to keep itself cool better.

This modem is a little bit bulkier in its design than some of the others that we have reviewed. It might make it slightly harder to conceal, but it also makes it seem sturdier, as if it would be much harder to break than some of the more delicate modems out there.
It does not come with a VoIP telephone adapter, but it does have a Gigabit Ethernet port to connect to your computer or to a router. It should easily work with any router that you decide to plug into it.
The SURFboard SB6190 works well for speeds up to 400 Mbps, making it a little faster than the average modem.

7. Motorola MB7420 Cable Modem
The final Spectrum compatible modem that we will review is the Motorola MB7420. This is another great modem from Motorola that will not disappoint you at all. It is high speed and works well for online streaming. It is really the best modem for just about anyone.
Like most Motorola modems are, the MB7420 has a tower design. This is ideal for a device as it allows better airflow to throughout the modem, allowing the components to stay cooler.

Looking at the performance of the MB7420, it comes with a DOCSIS 3.0 modem. This offers speeds up to 686 Mbps as well, which should keep you up and running at the speeds you want.

Factors To Consider When Looking For The Best Cable Modem For Spectrum
Before all else, you should make sure that the modem that you are looking at is compatible with Spectrum internet. If you find a modem is not compatible, it is never going to work for you.
Modems are not as versatile as routers are when it comes to compatibility, so you will need to make sure that the modem you choose to use for Spectrum is a cable modem, ideally one that states that it will work with Spectrum explicitly.
If your modem should work with Spectrum, but isn’t working, the first thing to do is to contact Spectrum and see what is going on.
Upload and Download Speeds
Advertised speeds are nice and all, but often they are a combined speed rather than the speed you actually want to know about.
When it comes to streaming or gaming, it is the download speed that really matters, not a combined possible speed. Upload streams do matter as well, it is really the download speeds that you should focus on.
Often when you have a good download speed, the upload speed will also be decent anyway. When a modem states a speed, check to see whether it is talking about combined speeds or download speeds.
Security should always be a factor when looking for the best cable modem for Spectrum. There are so many different forms of malware out in the world that it can seem all too easy to get a virus or have something malicious get into your network. Your first line of defence is really your modem.
Part of this would have to do with the type of chipset that your modem has, as Puma chipsets have been revealed to have some major security issues. Otherwise, see what kind of firewall your modem might have to keep the network protected.
The amount of Ethernet ports should be another consideration when it comes to choosing the best modem for Spectrum internet. Most modems will come with only one Ethernet port, which is enough to connect your modem to a computer or router, but nothing else.
When you have two Ethernet ports, you can hook up a router while also connecting your modem to a television or a gaming console, or even a computer. If you are not going to have a lot of streaming on your network, the amount of ports might not matter as much.
DOCSIS 3.0 vs. DOCSIS 3.1 Modem
Cable modems are normally labelled with either DOCSIS 3.0 or DOCSIS 3.1. Anything lower should simply be ignored. The DOCSIS 3.0 has at least four channels to increase the flow of traffic throughout your network.
The DOCSIS 3.1 protocol increased the size of the channels, so it can easily carry larger amounts of data at one time.
DOCSIS 3.1 modems are future-proof, so that they should be able to handle faster speeds when they become available. DOCSIS 3.0 are limited by what is available, so it technology improves, they will become obsolete, where the DOCSIS 3.1 modems will not. DOCSIS 3.0 are still perfectly adequate for today’s needs.
Typically DOCSIS 3.1 modems have enhanced security features as well as reduced packet latency and use less power than the DOCSIS 3.0 modems do. The packet latency is important for anyone who games and needs improved voice quality for VoIP calls.
Once you have decided that you really need to buy your own modem for your Spectrum internet, you need to buy the best modem for Spectrum possible. Our choice is the Motorola MB7621 modem, because it comes with all of the speeds and security features that the average network needs.
If you need a modem that offers higher performance options, the Netgear Nighthawk CM1200 is a better choice since it can handle those needs. If you prefer a built-in router with your modem, you should use the Motorola MG7550.
Regardless of the modem you choose, most anything will be better than what Spectrum offers.
