Actiontec (GS503AD3-01) Modem

Lights on my modem are flashing rapidly in unison. The power light is flashing red, connection light is blank, internet light is blank, and each of the four ethernet ports are flashing green. I have pressed the reset button the back of the modem, checked and rechecked all the connections, plugged the modem into an alternate power source...no change.

--If the Power light is flashing red thanits definately problem with the Actiontec Router --As you have checked with different power source, the possibility of bad power source is no more --May be due to some voltage fluctuation the modem is gone bad.

Lights are flashing rapidly. Have turn power off for 1 min. Lights are still flashing as before. Have check the cords and everything is connected. This has gone on for a long time. When trying to get help...
I would turn it off for longer. Perhaps 5 minutes. Try again. If the problem continues; you could try a firmware/software update. Here is a link to the specific site for this device. http://www.actiontec.com/support/product_details.php?pid=75

Trying to change from actiontec gt701 to actiontec gt701-wg. after new modem is hooked up, internet light stays red. switched by to old modem and all is fine. anyone know why internet light stayed red?
The reason why your internet light is red for the actiontec gt701-wg is because it is not yet configure. You need to access the gui of this router. enter the username and password for your internet connection. You can contact your ISP provider so they can walk you through for the steps on how to configure your new router.

The old router has green light because it was already configured by your ISP provider.

When power switch is turned on the Power light is rapidly flashing & the 4 Ethernet lights are flashing. The box is Actiontec GT704wg
I do not have a solution to the problem. However, I am having the same problem. This morning the Actiontec GT704WG power and ethernet lights were rapidly flashing. The modem was non-functional. I could not even connect to the modem through the browser to see if I could find a problem.

The problem lasted a couple of hours. Then all of a sudden the modem started working again. I won't be able to tell if the problem recurs until I restart the modem. And if the problem does occur again, I won't be able to connect to the internet.

LIGHTS ON MODEM ARE FLASHING RAPIDLY, HAVE CHECKED POWER SUPPLY AND PUSHED RESET BUTTON, NO CHANGE
You will have to be a bit more clear on which lights on which model of modem is flashing rapidly.
Usually, as long as the internet works, the flashing lights are there to show that the modem is functioning properly and is currently sending packets, transmitting data, etc.

Power Light Is Red, Internet Light Is Green, Other Lights Off
Check cable connections.

Try unplugging router from power for five minutes.

If that does not work call Internet Service provider to check if there is a problem with their server.
