Optimum Approved Modems

Just like every major cable internet provider, Optimum has their own list of compatible modems. However, unlike the official list, my list excludes a lot of bad quality modems. I’ve spent 11 weeks testing various modems with different internet plans and am finally here with a list of 9 best modems that work with Optimum.

One of the most important things to consider when purchasing a modem is to make sure that it is compatible with the internet provider and is suited for your internet plan. If it isn’t, then you won’t be able to use the internet. If a modem is compatible, but isn’t suitable for your internet plan, then you won’t be able to get the speeds mentioned in your plan.

Although, you can rent one but as per my research, buying a modem/router provides a better ROI. However, you can’t choose a random modem, you’ll need to make sure that the modem works with your Optimum and is capable of handling the internet speeds according to your internet plan.

Also, it’s not just Optimum, majority of the cable internet providers in the US including big players like Comcast Xfinity, Spectrum, Cox, have a pre-approved list of modems that are compatible with their network. This is generally their way of forcing you to asking you to rent internet equipment over buying.

It doesn’t matter what Optimum package you are on, whether you are on Optimum’s 1 Gig (Gigabit plan) or the medium-end Optimum 500 (download speeds upto 500 Mbps) or the slowest Optimum 300 (300 Mbps), the modems in our list will work with your service package.

The Best Modems For Optimum [Approved & Compatible]

Since you’ve decided to purchase a modem or a modem/router combo that works with Optimum, my job is to help you find a modem that’s not just compatible, but is also suited for different internet packages on Optimum.

For a smoother internet browsing experience make sure that the modem you’re getting has a bit of extra capabilities than your internet package. For instance, if you’re on Optimum 300, consider getting a modem that has download speeds above 300 Mbps (300-400 Mbps.)

It is suited for people who have internet plans with speeds in excess of 300 Mbps. For instance, if you’re on the Optimum 300 service package, there would be no point in buying this, as you won’t be able to use it to its fullest potential.

Such high bandwidths are possible due to its 32 x 8 channel bonding. You will be able to touch download speeds of up to 1750 Mbps and the uploading speeds shall be super fast. Everything from streaming 4K videos on Netflix/YouTube to downloading 40-50 GB of games shall be fast and smooth.

The build quality of the entire modem is sturdy. It is black in color and is made of metal and plastic. It has a blue light on its icons, which makes it look futuristic.

3. Best From Netgear: Netgear CM700

The Netgear CM700 is a DOCSIS 3.0 Gigabit cable modem that’s best suited for the Optimum 1 Gig plan and for Optimum business package owners.

It offers a maximum download speed of 1.4 Gbps. When you first look at this device, it does not even look like a modem, thanks to its unique trapezoidal design. It has mini triangle cuts all around its body, and overall it looks very stylish.

A total of 32 channels are available for download on the Netgear CM700, and 8 for upload, which means that your internet speed will be superfast. You will be able to get the best out of your WiFi plan, no matter which service provider you choose.

Apart from being an excellent modem, the Netgear CM700 will also act as a Cable provider. It is a 2-in-1 device, so you can return your current cable modem after you purchase it.

In terms of compatibility, the CM700 has been certified by Optimum, Xfinity, Charter Spectrum, and more. Whichever cable internet provider you choose, just make sure to get the highest Gigabit plan to make the best out of this modem.

For Optimum, that would be the 940 Mbps plan (Optimum 1 Gig), which costs around 80 dollars per month. However, you can even use it if you are on the Optimum 500 plan, because it’s future proof and won’t have to be replaced if you’re getting a free speed upgrade.

The only downside of this modem is its single Ethernet port. You can not connect it to more than 1 device at once, which might be a deal-breaker for a lot of you, especially if you have multiple devices you would want to connect. So, make sure about your usage, before you settle with it.

The weight and dimensions of this modem are absolutely ridiculous as it measures just 6.6 x 5.2 x 1.7 in inches and weighs 0.55 pounds only. It is one of the lightest modems in the entire industry.

4. Best For Optimum 500: Motorola MG7550

The Motorola MG7550 is a high-performance premium modem that you can purchase for around 180 dollars. It is ideal for the Optimum 500 internet package. However, a lot of them on the Optimum 300 service pack also consider it.

The modem looks premium and has a very sturdy build quality, which is expected since it comes at a premium price. Despite being sturdy, it’s lightweight. However, it’s a bit expensive compared to many options on this list.

According to the box, the modem can touch speeds up to 1900 Mbps, but you will need a separate WiFi power boost. So, the actual speed without any boosters is around 686 Mbps, which in itself is not bad. The best thing about this is, you can simply get a WiFi power boost when you upgrade to a faster plan.

Streaming videos in the highest of resolutions and downloading massive games will not be of any trouble to you. Internet plans of above 400 Mbps would be ideal for a modem of this power. You will be able to hit similar speeds that I have mentioned above.

Apart from its Coaxial cable slot, there are 4 LAN Ethernet ports on the back of the modem. A yellow sticker marks them, and you can use them to connect it to multiple devices across your home.

The TP Link TC-7620 is a budget-friendly high-speed modem. It supports speeds up to 686 Mbps while downloading and 143 Mbps while uploading.

The design and build quality of this modem is okay. They are not the best but will get the job done. There are numerous small holes on its side panel for keeping the internals cool, and they do that job with excellence. But, they also make it look a little bit old fashioned and out-dated, so it is a give and take relationship.

There are a total of 16 download channels and 4 upload channels on this modem, which ensure that you get an uninterrupted fast internet connection. The WiFi plans that you opt for this purpose should be around 300 to 400 Mbps, but not above them. It is not equipped to deal with gigabit speeds, so avoid those plans.

The Arris Surfboard SB6183 is a 16 x 4 cable modem, which means it has 16 download channels and 4 upload channels. The higher these numbers, the better speed you will get, so this particular model is better than 8 x 4 modems, but inferior to 32 x 8 ones.

The build quality of this device is mediocre. It is chunky, and the plastic used on its body is fragile. I would recommend you keep it in a safe and secure place, away from children.

The maximum download speed that you can get out of this modem is 686 Mbps, which is excellent if you aren’t on a Gigabit plan. Your movies will download within the blink of an eye; however, bigger games might take some time.

Optimum plans of up to 300 Mbps would be ideal for this modem, as they are the only ones that are within its reach. Any plan that is more powerful than this will be a bit too much for the modem to handle.

Frequently Asked Questions

The Verdict

All of the modems that on this list are equally good (I’ve already filtered out the bad options.) You can choose any one of them, and it will get the job done. However, make sure that the one you’ve chosen is capable of handling the internet package you’ve subscribed to.

Also, a few modems in this list have limited ethernet port slots, in case you’re having multiple devices to connect, you should consider avoiding them. Make sure to conduct a thorough research about all the aspects of the modem before you finalize.

Although not needed, but many cable internet providers stop supporting modems when they feel like. Getting a confirmation from your cable provider about the modem compatibility could help you save time and money.
