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. To reboot the modem, press and hold the indented Reset button for three to four seconds. To restore factory defaults, press and hold the indented Reset button for more than 10 seconds or until the front panel LED flashes.
    • ETHERNET - Connects to the 10/100/1000 Ethernet ports on your computer.


Devices should only be plugged into Ethernet port 1, 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.
