Optimum’s internet plans are value for money but the internet connectivity equipment they provide for the lease is most of the times outdated or isn’t capable of handling high-speed plans.

Despite being on a high-speed 100Mbps plan, there are chances that you won’t be able to use it at its fullest potential. It is because of the outdated equipment. And what hurts the most is, you end up paying between $4.95 to $9.95/month as a lease rental, which is almost $120/year.

Well, you can continue being lazy, stick to their outdated equipment and continue experiencing internet outages or slow speeds or you can cancel the modem/router lease and buy the one that comes with the latest technologies, features and saves money.

We know that you must be busy watching movies and shows on Netflix or Amazon Prime and don’t have enough time to visit a store to choose a cable modem/router that works with Optimum. That’s why we decided to test the modems or modem/router combos approved by Optimum and came up with the list of the best-rated models that are performed really well in our compatibility tests.

When it comes to finding the best modem for Optimum ISP, we would always advise you to opt for a standalone modulator-demodulator, instead of a combo. While a modem-router combo can be cost-efficient, to begin with, they do not allow you to upgrade to speedier connections in the future. Considering each of the mentioned aspects, it is advisable to invest in the NETGEAR CM700 as your modem for choice.

Coming to the layout, the NETGEAR Cable Modem CM700 assumes a sharp and aggressive design that is bolstered by green LEDs, angled edges, upright stature, and niftily vented chassis. The performance-centric CM700 exhibits the DOCSIS 3.0 technology, which readily translates into higher speeds and stable connections. Based on the availability of 32 downstream and 8 upstream channels, it would be possible for this modem to download at least 175MB of data each second, riding on the laurels of the potential service bandwidth of 1.4Gbps.

Therefore, this modem can be purchased precisely for the Gig cable plans offered by Optimum, which are mostly in the range of 940Mbps. As it is a standalone modem, you can reach excellent download and upload speeds even if the attenuation is accounted for. For instance, our experts using the Optimum Gig plan could get maximum download speeds of up to 680Mbps and upload speeds of almost 130Mbps, even during peak hours.

Besides, the NETGEAR Cable Modem CM700 is also one of the few future-proof cable modems that you should invest in, owing to the Channel Bonding technology. While some might still prefer modems with 24 x 8 channel density, 32 x 8 allows you to operate at the highest possible speeds even during network congestion. It comes in handy when online schooling, video conferencing, live streaming, etc. is concerned.

Coming to the compatibility, the NETGEAR Cable Modem CM700 isn’t just Optimum approved but also offers support for the Comcast, Spectrum, and COX ISPs. Therefore, it shouldn’t be hard enough to identify the most compatible router with this machine. However, if you want to steer clear of network attenuation, there is a Gig Ethernet port for helping you plug-in the modem directly to the PC, precisely to reach the highest possible download and upload speeds.

Coming to the usability quotient, the NETGEAR Cable Modem CM700 comes equipped with the QoS enhancement for excellent HD streaming, a feature that automatically helps you avoid network issues and scale beyond for the highest possible speeds. Besides, you also get access to the auto-sensing technology that gets you close to the highest download speed potential.

Finally, this is one of the few modems in the market to feature 128MB of RAM for storing firmware details and the configuration essentials. Nonetheless, the 8MB of flash memory is also useful, considering the QoS functionality in play. Therefore, if you are in the market for a fine and future-proof Optimum-approved modem, the 0.55-pound NETGEAR Cable Modem CM700 is the perfect gadget to invest in.

Frequently Asked Questions

Which is the most affordable router for Optimum?

In our compatibility tests, we found the CISCO DPC3212 to be ideal and cheap. Over a week of use, we found that it was quite easy to set up, and Optimum’s care was quite helpful. The ping and latency were minimal, and browsing was smooth and reliable. We hooked it up to two different UHD television sets and a couple of laptops, and all of them were capable of downloading at least 25Mbps individually. Its download and upload performance were commendable and smooth. A perfect device, but of course, you must have a plan with high speed to take advantage of it.

Which is the best telephony modem for Optimum?

The Arris TM822A Touchstone is ideal as a VoIP solution. Why pay for long-distance when a small VoIP subscription can save you hundreds of dollars every year. It showed quite impressive performance with over 150 Mbps downloads. There was no lag or throttling, and never did we see streaming video buffering. All that you need is to attach a router to the Ethernet port, and you will have a secure wireless signal across your property at blazing speeds.

Which one is the most advanced Optimum compatible modem?

With the DOCSIS 3.0 technology, the Arris Touchstone TM1602A is an ideal modem to buy for your home network. The 24 x 8 channel bonding is capable of over 900Mbps download speeds. That is close to 1Gbps or a movie every 2 seconds. There was no latency at all, and we could surf the web just as we wanted with video conferencing, 1080p YouTube videos open on multiple tabs, and Google Duo calls. The rear panel is equipped with an Ethernet port and two ports for plugging in phones. You could set up a router to work with the device and enjoy Wi-Fi through your house.

The Verdict

On calculating we found out that, you’ll end up spending $120/year as a rental for equipment. You can buy a much better modem/router for half of the price and own it which will provide much better performance.

Besides, it’s not just about the money alone, it’s about getting value for the money. The modem and router that’s provided by them aren’t really capable of the high-speed plans. Therefore you could experience throttling while surfing the web.

A few of the Optimum compatible modems on this list have capabilities even above the ISP’s high-speed plans. So, if there’s an upgrade in the network and you get it for free, don’t worry, the equipment from our list should be able to handle it well! So which cable modem are you getting?

  1. I still have a landline because I live where cell phone is spotty. I have Cablevision, but I can’t seem to find a compatible modem that has a phone jack. My router is Netgear.
