WNDR3400V3 will not connect to modem

I am no longer able to connect devices wirelessly or wired to this router. 

I have already tried:

  • rebooting and resetting both the modem and router
  • updating to the latest firmware (1.0.67)
  • replacing the cable between modem and router
  • verifying the MAC address

I am getting signal from the modem (Arris TG1862G) when I hook devices direct to it.  The router is not acquiring an IP address from the modem and the internet indicator LED stays solid amber.

       "no longer"?  What changed?  "not able" is not a useful problem
    description.  It does not say what you did.  It does not say what
    happened when you did it.  As usual, showing actual actions with their
    actual results (error messages, LED indicators, ...) can be more helpful
    than vague descriptions or interpretations.

       That's a modem+router, not a simple modem.  Generally, cascading
    multiple routers is undesirable.  If the purpose of the WNDR3400v3 was
    to extend the wireless-network coverage of the TG1862G, then you might
    want to configure the WNDR3400v3 as a wireless access point.  (If its
    purpose was something else, then please reveal.)

     

       Visit http://netgear.com/support , put in your model number, and look
    for Documentation.  Get the User Manual. Read.  Look for "AP Mode".


    > [...] The router is not acquiring an IP address from the modem [...]

     

       How, exactly, did you determine this?  See "As usual, [...]", above.

     

    > [...] the internet indicator LED stays solid amber.

     

       That's one LED out of what, ten?

     

       Can you communicate with the management web site of the WNDR3400v3
    from a computer/device which is connected to it?

     

    > o updating to the latest firmware (1.0.67)

     

       Huh?  Visit http://netgear.com/support , put in your model number,
    and look for Downloads.  (For older versions, under Firmware and
    Software Downloads, look for "View Previous Versions".)  When I do that
    for "WNDR3400v3", I see nothing like "1.0.67".


    > o replacing the cable between modem and router

     

       For a quick cable test, connect each end to a LAN Ethernet port on
    the WNDR3400v3, and observe the relevant port-status LED indicators.

     

    > o verifying the MAC address

     

       "verifying" what/where/how, exactly?

      I have always had three devices connected to it:  the PC on port one, an Android TV box on port two, and a Samsung smart TV on port three.  I have not changed anything in this configuration since I installed it.  The router worked for months until suddenly it stopped working.  While I seldom used the wi-fi, I can confirm it ceased working at the same time.

       

      Per the manual on page 12, the presence of the internet LED in solid amber would indicate "The IP address was not acquired."  I can perhaps screenshot the Genie program if it might help.

        I promote isolate, divide and conquer and validate.

        Get your LAN down to it's simplest form...

        In your case, probably Modem/Router --> device

        Verify that you have a working LAN with the simplest of configurations.

        Add pieces of equipment individually one at a time confirming that each operates properly.

        In this respect, you are verifying Internet>Cables>Equipment Operation and it's easy enough to do.

        Once you are convenced that you have all good equipment and cables and signals up to the WNDR and that it is the isolated problem, save a copy of the configuration, download local a copy of the latest firmware, reset the WNDR via the reset button, get back into the WNDR, do a firmware update from the local file, then try again.

        Is the cable from your modem going into the yellow port on the back?

        You may need to do some port forwarding on the Modem/Router and set the WNDR up for a static WAN IP.
