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.

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 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.
You can purchase the Netgear CM700 for a price of 98.99 dollars, and it comes with a warranty of one year.

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.

Frequently Asked Questions
The answer to this question lies inside your internet package. If you have higher speed packs, you will need a more expensive modem to get the best out of them, and it goes the same for smaller ones, only less money. So, choose the one that fits your budget and speed.
If you do not have any gaming console or desktop right now, I would still recommend you get a modem that has at least 2 Ethernet ports because you never know what the future holds. It is smart to buy a product that is future proof.
The very first product that we discussed would be the most advanced modem on this list, and it is the Netgear CBK40-100NAS. It has incredible speed, excellent coverage, and a high quality-price ratio. I do not see any other product outshining this one.
Buying a modem is far more economical than renting one. On average, you will save around 120 dollars within the first year of your purchasing which is a cost you’ll pay for a decent modem. So, without a doubt, I would recommend you to buy one.
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.
