Issues with Blinking Red Broadband or Services Down
If you have a Blinking or Solid Red Broadband light, resetting the modem and checking cables and connections is recommended:
Restart Gateway : Unplug the power connection behind the gateway for ~15 seconds.
Plug back in and wait for the broadband light to go green, this can take 2-5 minutes.
Reset the Modem: Press and hold the reset button located on the rear of the modem for 20 seconds. This may get your services up and working. You can also log into the modem to reset it. Click here for more information on how to reset the modem.
WARNING: This will return all gateway settings to a default state. Any custom Wi-Fi passwords, Wi-Fi names, SSID, Static IP, and Port Forwarding rules will be lost.
Check the Connections: they can loosen if bumped into. Sometimes cables are unplugged by mistake. Remove all surge protectors, battery units, and other equipment so that there is a direct connection.
Also, please be wary of any change that may have occurred around the time service dropped like: adding new equipment, storms, power loss or something out of the ordinary.
