N450 CG3000Dv2

N450 modem, Wi-Fi works fine, no Ethernet access. Lights for ports 1 and 2 are amber and do not change when a cable is plugged in. Windows 10 laptop will not connect, neither will home security NVR. What could the issue be?

       All ports?

       What about ports 3 and 4?

       Bad hardware?  A bad cable could keep a LAN-port LED indicator off,
    but if it's on ("amber") when no cable is connected, then that sounds to
    me like a bad port.

       If any LAN Ethernet port still works, then a cheap Ethernet network
    switch could let you expand the LAN from a still-working port.  If
    they're all dead, then your reasonable choices would seem to be a
    less-broken modem+router (or modem and router), or to use only wireless
    connections (which sounds as if it would be unsatisfactory).

       According to the Model N450/CG3000Dv2 User Manual, the LAN Ethernet
    ports can be disabled/enabled in the modem+router's management
    interface (Advanced > LAN Switch).  If you get desperate, a settings
    reset might be worth a try.

       If you don't already have the appropriate user manual for your
    device, then visit http://netgear.com/support , put in your model
    number, and look for Documentation.  Get the User Manual.

      Hard resets have been done with no change. Lights on ports 1 and 2 are dimly lit amber, plugging cable in changes nothing on any ports. My options for Lan Switch are grayed out.

        Have you checked with your ISP if the modem is coded correctly it could be in modem only mode for some reason and the ports are not working.
