MAC Address and Network Name (SSID)

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.

Initial installation requires that the Network Name (SSID) and password be changed. The Network Name (SSID) and password listed on the bottom of the device are only used to connect to the modem during the initial install. Technicolor recommends that a single Network Name (SSID) is used for the CGA4131 because the modem automatically chooses the best network for each connected device. Ensure all WiFi-ready devices recognize the single Network Name (SSID).
