Pulsing red light on router

my netgear 12 router has a pulsing red light.  the light icon is a circle above a line above two circles.  I have power cycled both the router and the modem, same situation.  I have accomplished a router factory reset and the light is still pulsing red.  I checked internet speed and it is above 600 mb so that is good.  I have reseated all cables on the router.  I haven't contacted the internet provider yet since I don't know what the pulsing red light is telling me.  Thanks for any help.

        Although it looks red, it is actually amber.  (Not unusual, lots of Netgear's amber LEDs appear red to me in some lighting conditions).

         

        The 4 ethernet LAN ports on the back or your router support gigabit ethernet.  The amber color means that at least one of these LAN ports has negotiated a slower speed (usually 100 mbps, but it could even be 10 mbps).  It is pulsing because there is traffic going to/from the ethernet-connected devices.

         

        This is not necessarily an error - there are plenty of wired devices out there that use fast ethernet instead of gigabit.  Printers, IoT devices, TVs etc.

         

        But it could also be a faulty or old ethernet cable or a bad connector on the router.  If you can give us more info on what you have connected to the LAN ports, we could help you figure that out.

    Do you mean the AX12 (RAX120)?

     

     

    If you do, can you look at section 1 in the manual, and let us know more precisely where you are seeing this?
