Generally, we will be responsible for installing a new cable drop near your computer. We also will install the cable modem, if you prefer. Below you will find some basic information and tips about Suddenlink’s cable modems.

Cable Modem Lights

External cable modems have front panel indicator lights that show the status of the cable Internet connection. The exact labels for these lights will vary between manufacturers, but all external cable modems have lights that indicate similar information. You can use the information provided by these indications to demine the status of the modem.

  • One light indicates when power is available and the modem is turned on.
  • Another light indicates a connection (block sync or synchronization) with the cable network.
  • One light will indicate a working connection to your PC.
  • Another light (or two) will flash to indicate that data is being transferred—if there are two such lights, one light flashes when your modem sends data and the other flashes when your modem receives data.
  • Some modems have a test light or one that indicates a modem error.

Helpful Tips

  • Plug your cable modem into a surge-protected 110-volt power strip.
  • The cable modem must always be in an open, well-ventilated area. Do not put the cable modem in a confined space or place books, files or other desktop paraphernalia on or next to it.
  • After moving or installing your cable modem, you must check the modem lights for the proper indications. If you don't get the proper indication of lights or an internet connection, do not proceed any further. Contact Suddenlink High Speed Internet Customer Support.
