7 Best Optimum Compatible Modems in 2021 [Approved & Certified]

Are you in search of a cable modem that works with Optimum? Perhaps, you’re tired of paying the overpriced equipment rental and think that purchasing networking equipment is better than renting. However, you can’t just pick any random modem and connect it, you need to get the one that’s certified/approved by Optimum.

Just like Xfinity, Spectrum, Cox, and majority of the internet service providers, even Optimum has its own list of compatible modems. But their official list also includes a lot of bad modems, that can cause issues such as high-latency, throttled internet connectivity, packet loss, etc.

You can make a search and you’ll find an endless list of Optimum compatible modems, but there’s a chance that they might include the bad modems too. I faced this, that’s why after spending 11 weeks testing various modems with different service packs from Optimum, I’ve made this list of 7 best options.

While you need to get a modem that’s compatible with Optimum, you’ll also need to make sure that it’s also suited for the service pack or internet plan you’ve subscribed to. For instance, you can’t expect a low-end modem to handle gigabit speeds of the Optimum 1 Gig plan.

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 up to 500 Mbps) or even on the slowest Optimum 300 (300 Mbps), you’ll be able to find a modem in this list for your internet needs.

Best Optimum Compatible Modems in 2021

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 few extra capabilities than your internet package. For instance, if you’re on Optimum 300, consider getting a modem with download speeds above 300 Mbps (300-400 Mbps.)
