Nighthawk AC1900 C7000 LAN ports don't work, but full WiFi

Help! We just removed our Orbi from our system and the AC1900 C7000 LAN ports are no longer working. Blinking orange lights. WiFi is just fine. Ethernet cables are in perfect condition, even tried different ports. Tried powering off/on the router, too.

   C7000 or C7000v2?  Look for "Model" on the product label.

   Which kind of "no longer working" is that?  Which lights do what,
exactly?  What's connected to what?

 

   "no longer working" 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 (commands) with their actual results
(error messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations.

 

> [...] Ethernet cables are in perfect condition, [...]

 

   You determined this how, exactly?


> [...] even tried different ports.

 

   "different" from what?

 

   Visit http://netgear.com/support , put in your (actual) model number,
and look for Documentation.  Get the User Manual (at least).  Read.
Look for the LED descriptions and "Troubleshoot".  Further reading might
not hurt, either.

   Did you try a settings reset?  Look for "Factory Settings" in the
User Manual.

Model: C7000v2. 

 

Two of the ports, into which the ethernet cables are connected, are flashing orange. They are connected to an ADT Security System control panel and a Philips Hue control panel. They do not provide network connectivity to these devices. They worked just fine when we had the Orbi connected.

 

Ethernet cables are not damaged in any way, shape or form. They worked just fine prior to removal of the Orbi.

 

Different ports - moved the cables between ports. Any port the cables plug into flash orange.

 

Tried troubleshooting with the Test the LAN Path to Your Modem Router details in the manual. Works fine.

 

Did a factory reset right after removing the Orbi. Have not tried it again since then, but it didn't fix it then.

 

Thanks.

   "the ports" "are flashing orange"?  Are there LEDs embedded in the
Ethernet connectors on this modem+router.  How many?  Which color(s)?
(I don't have an example, and I don't see them mentioned in the User
Manual.)  "flashing", if it follows a cable, typically indicates
activity, not a problem.

   See "not a useful problem description [...]", above.

 

   What happens if you connect two of those LAN ports together using one
of your must-be-good Ethernet cables?  Generally, "orange" (what Netgear
calls "amber") could just mean a 10/100MHz link, rather than 1000MHz.
This is not a defect, if the connected device does not have a gigabit/s
interface.  An (unspecified) "ADT Security System control panel and a
Philips Hue control panel" sound to me like slow (sub-gigabit/s)
devices, for which an amber LED might be normal.

 

   Do those devices appear in an Attached Devices report on the C7000v2
management web site?

 

   What, exactly, was your "our Orbi"?  Did it use the same IP address
range (subnet) as the C7000v2?  Have you tried resetting and
reconfiguring the uncooperative devices?
