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 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.

Note: The default SSID and password are listed on the bottom of the device. To change these, use the Panoramic Wifi app or web portal at wifi.cox.com. After a factory reset, the SSID and password revert back to the default.


The lights indicate the current status of your WiFi modem. To troubleshoot any connection problems, use the table below.
