It's Optimum, or it's not.®
Installation
Installing Optimum Online is easy. Simply follow three simple steps:
1. Connect Cable Modem To Cable Line
Be sure to split your cable at the earliest point of entry in your home using the cable adapter (splitter) we supply.
2. Connect Cable Modem To PC Using USB or NIC/Ethernet Card
If you are using a USB port, simply plug the USB cable into the back of the cable modem, then into the back of your PC.
If you are using a NIC/Ethernet Card, install the card first. Next, plug the RJ-45 cable into the back of the cable modem, then into the back of your PC.
Note: USB cables will not work with Apple Computers. For maximum speed, we recommend connecting via Ethernet.
3. Activate Your Account
To set up your account and e-mail, insert the Optimum CD and follow the easy on-screen instructions. The CD can be found in your Optimum Self-Installation Kit.
