New customers – Start here

If you’re a new customer with Optimum, use your phone camera to scan the QR code on the packing slip that came with your shipment. The code will take you to a website that will help you install and activate your new equipment.

All other customers –please follow the instructions below to replace your equipment.


Disconnect everything from your existing equipment.	Connect the open end of your coaxial cable to the back of the new Gateway.


Plug the Gateway power cord into the back of the device.	Plug the other end of the power cord into an electrical outlet.


The Gateway is ready for the next step when the top 3 lights (POWER, DS/US, ONLINE) on the front panel are solid green. This may take a few minutes.	Sign in at optimum.net/gateway to personalize your in-home WiFi network name, also called an SSID, and your password. Can’t remember or don’t have an Optimum ID? Visit optimum.net/idhelp If you’d rather use the defaults, look at the label on the bottom of the Gateway. Note, that your password will be listed as the “Wi-Fi Pre-Shared Key”.


To connect to the Internet, go to WiFi settings on your device. Select your in-home WiFi network name from the list and when prompted, enter your password. Repeat this step for all of your connected devices.	If you have an Altice One Mini, you need to re-pair it to the Gateway. Refer to the “Replacing an Altice One Mini” instructions at optimum.net/guides. If not, you’re all set!

Make sure to return your old equipment. Learn how at optimum.net/return
