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 The list is so outdated on optimum website but wanted to let everyone know this does work with optimum.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

This was the perfect modem for me. Setup was a breeze and it’s compatible with my service provider. Wish I would have made the purchase years ago! A fast, reliable modem.

The Aris modem was easy to install and setup. I like that the housing has plenty of ventilation holes for the heat to escape. The form factor is small and the feet have a good grip to them so it stays upright. The status lights are easily readable and the modem has proved reliable so far. I am happy with my purchase.
