This works for Optimum/Altice! The list is so outdated on optimum website but wanted to let everyone know this does work with optimum. This Modem is amazing! I get my 1 GBPS speeds with no issues! It is also so easy to setup with optimum. All you need to do is go to https://install.optimum.com/ put your account information in. Make sure to do this from your cell phone. Unplug the old modem and plug in the new modem. Say yes to the questions asking if you are replacing modem, Enter the MAC address for the new modem. Hit next. It will detect the modem and ask you to make sure you are replacing the old modem that is in place by checking the Mac address. Click next and it will send a reset command to the new modem. If the lights reset on your new modem you are all set. It may take 15 to 45 minutes before you get internet although my situation was instantly connected to the internet. I get 100% of the speeds I pay for. Hope this helps someone researching for a modem for Optimum. This also has DOCSIS3.1 for future upgrades and is also backwards compatible to DOCSIS3.0
We were using an Xfinity “brand new” modem. The modem was massive, yet it covered only the living room of our house. Even so, it was difficult just establishing a connection through our phones while in the living room. The Xfinity brand box was terrible AND we were paying them to have it in the house. The internet speed was also extremely terrible for the price that we were paying. This modem is small, yet so powerful. It covers the entire house with our Google Nests. I’ve been working while someone else has been gaming, and vice versa. The connection has never slowed down. It was extremely user friendly and took about less than 15 minutes to replace our old one with after a hard google search. Perfect for multiple users but I would downgrade to the cheaper product that the brand offers if you’re a single user who’s not looking to do multiple internet based things at once.
