Follow these steps below.

1. Unplug the modem from its power source
Once your modem is unplugged, all of the lights on the modem should go off. If the lights are on after you disconnect it, you may have a battery backup that also needs to be disconnected. So go ahead and disconnect that, too.

2. Unplug the router from its power source
Not sure if you have a router? Routers are connected to your modem with an Ethernet cord and will have several additional Ethernet ports to manually connect computers. Common brands include Linksys, Netgear, Cisco, Belkin and D-Link.

3. Tighten the coaxial cable connector on your modem
Use your hand or a small 7/16-inch wrench to make sure the cable connection is secure.

4. Reconnect the modem to its power source
Wait until it has fully restarted and the lights on the modem turn on. This can take up to a few minutes. And if you use a battery backup, be sure to reconnect it now.

5. Reconnect the router to its power source
Wait until it has fully restarted. This also can take up to a few minutes.

6. Check your internet connection
Open your web browser and visit optimum.net. Once the page loads, you'll be good to go.

Not connected? Unplug the modem and router again, restart your computer and then repeat Steps 3 - 6. If you are still having trouble, contact our customer service team.
