The following ports are available on the back of the modem.

    • RESET - Use this button to reboot the modem or restore to factory defaults. It is recessed to prevent accidental resets. Press and hold the indented Reset button to reboot the modem for three to four seconds. To restore factory defaults, press and hold the indented Reset button for over 10 seconds or until the front panel LED flashes.
    • ETHERNET - Connects to your computer's 10/100/1000 Ethernet ports.


Devices should only be plugged into Ethernet port one because only one port is active. Therefore additional devices plugged into the other ports will not receive Internet access.

  • CABLE - Connects to the cable wall outlet.
  • POWER - Connects the modem to the power cord.
