While renting your modem and other networking equipment can be very convenient and save time in the short term, you will be charged a monthly rental fee for your modem on your service bill. That $10 per month charge definitely adds up! Imagine how much you could save in just 1 year just by owning your own Optimum approved modem! That’s a lot of chocolate croissants — or whatever… We don’t want to be bossy!

Finding the right model can be tricky, especially with Optimum’s very selective criteria for compatibility. To make things easier, we’ve pulled together a list of all models that have been tested and confirmed to work well with Optimum cable. Our Optimum approved modems list features models that are on Optimums official list, as well as models that have been tested to meet Optimums requirements AND have been successfully activated recently by our customers.
