Detailed Breakdown of Spectrum Modem Lights

A solid green light means the modem is online and connected. If the light is red or off, there may be an issue preventing the internet connection.
Wireless Light
Modems with built-in Wi-Fi include a wireless light that indicates the status of the wireless network. A solid green light shows that the wireless network is broadcasting normally, while an off light means the Wi-Fi connection is disabled.
