Flashing RedA POST failure (not bootable) or device malfunction occurred. When the device encounters a POST failure, all indicator lights on the front of the device continuously flash.
EthernetOffThe gateway power is off, There are no powered devices connected to the Ethernet ports.
Solid GreenPowered device connected to the associated port (includes devices with wake-on-LAN capability where a slight voltage is supplied to the Ethernet connection).
Flickering greenActivity seen from devices associated with the port (the flickering of the light is synchronized to actual data traffic).
WirelessOffThe gateway power is off. There are no powered devices connected to Wi-Fi.
Solid GreenWi-Fi is powered on.
Flickering GreenActivity seen from devices connected via Wi-Fi (the flickering of the light is synchronized to actual data traffic).
Wi-Fi SetupOffWi-Fi is not in use or not broadcasting.
Flickering GreenIndicates WPS is broadcasting.
BroadbandOffThe gateway power is off.
Solid GreenThere is a good broadband connection (i.e., good DSL Sync).
Flashing GreenThe gateway is attempting a broadband connection (i.e., DSL attempting sync).
Flashing Green and RedIf the broadband connection fails to be established for more than three consecutive minutes the LED switches to Flashing Green when attempting or waiting to establish a broadband connection alternating with a five second steady Red. This pattern continues until the broadband connection is successfully established.
Flashing RedThere is no DSL signal on the line. This is only used when there is no signal, not during times of temporary no tone during the training sequence.
ServiceOffThe gateway power is off, or the broadband connection is not present.
Solid GreenIP connected (i.e., the device has a WAN IP address from DHCP or 802.1x authentication and the broadband connection is up).
Flashing GreenThe gateway is attempting PPP connection, attempting IEEE 802.1X authentication, or attempting to obtain DHCP information.
Solid RedThe gateway attempted to become IP connected and failed (no DHCP response, no PPPoE response, 802.1x authentication failed, no IP address from IPCP, etc.) The Red state times out after two minutes and the Service indicator light returns to the Off state.
Phone 1, 2OffVoIP is not in use, line is not registered, or the gateway power is off.
Solid GreenThe associated VoIP line has been registered with a SIP proxy server.
Flashing GreenIndicates a telephone is off-hook on the associated VoIP line.

Status lights during firmware upgrades
Firmware updates keep your Wi-Fi gateway running smoothly.  During the software installation, you’ll lose internet and phone service.
The lights will function as follows:
  • As firmware is being loaded into flash, the lights will operate normally as described above.
  • The installation may take a few minutes. During this phase, the Power light will be Solid Green, the Ethernet light will be Solid Green, and the rest of the lights (Wireless to Phone 2) will flash Solid Green one after the other moving from top to bottom and then bottom to top.

The gateway will restart automatically. As the device reboots, the POWER ON light behavior will happen.
