After the gateway is successfully registered on the network, a single solid white LED illuminates continuously to indicate that the gateway is online and fully operational.

Important:

  • To help prevent errors during installation, connect the coax cable to a cable outlet first, then connect the power cord to an electrical outlet.
  • After connecting the modem for the first time, wait 10-15 minutes before attempting to complete the WiFi setup or get online. Do not unplug the modem from power or factory reboot the modem during the initial 10-15 minute firmware download and modem registration process.
  • During installation or after a factory reset, the default Network Name (SSID) and password must be changed. Until that process is done, internet access is blocked.

The Technicolor CGM4141 has the following ports and buttons.

  • TEL 1 / TEL 2 - Connects to home telephone wiring and to conventional telephones or fax machines. TEL 1 is used for the first line of phone service and TEL 2 is for a second line of service.
  • ETH 1 / ETH 2 - Two ports are available to connect to the 10/100/1000 Ethernet ports on your computer or other device. It is recommended that devices be hardwired if possible.
  • RESET - This is recessed to prevent accidental resets and is used to restore all settings to factory defaults. Factory resets result in the loss of all settings. To restore factory defaults, press and hold the indented Reset button for more than 10 seconds or until the front panel LED flashes.
  • MoCA LIGHT - When the solid white light above the coaxial input is on, MoCA is enabled and allows for connections to specific cable receivers.
  • CABLE COAXIAL INPUT - Connects the coax cable to the cable wall outlet.
  • POWER - Connects the power cord to the modem.
  • WPS - Located on the top of the modem, this button can be used instead of entering the WiFi password to connect wireless devices that support WPS to the Technicolor CGM4141. WPS works only for wireless networks that use a password that is encrypted with the WPA Personal or WPA2 Personal security protocols.
     

MAC Address and Network Name (SSID)

MACClick to enlarge.

 

MAC addresses are written as 12 digits containing both letters and numbers (0-9, A-F). A MAC address is unique. The first six characters of the MAC address are unique to the manufacturer of the device.

Notes:

  • The SSID and password listed on the bottom of the device are only used to connect to the modem during the initial install or after a factory reset.
  • Technicolor recommends that a single Network Name (SSID) is used for the CGM4141 because the modem automatically chooses the best network for each connected device. Ensure all WiFi-ready devices recognize the single Network Name (SSID).
