NightHawk AX8 won't detect cables

As per the (no so*) fine manual referred, p,162 - the Internet LED is lit if (lit white on Gigabit?) Ethernet connection is established:

===

"The Internet LED on the router is lit if the Ethernet cable connecting the router and the modem is plugged in securely and the modem and router are turned on."

===

Further on, p.163

===

"Internet or Ethernet Port LEDs Are Off
If either the Ethernet port LEDs or the Internet LED does not light when the Ethernet connection is made, check the following:
• Make sure that the Ethernet cable connections are secure at the router and at the modem or computer.
• Make sure that power is turned on to the connected modem or computer.
• Be sure that you are using the correct cable. When you connect the router’s Internet port to a modem, use the cable that was supplied with the modem. This cable can be a standard straight-through Ethernet cable or an Ethernet crossover cable."
===

One can expect that the Internet LED does come up when "just" an Ethernet link can be established - and not a succesful Internet connection, e.g. using the right encapsulation, authentication, IP address assigned, DNS, ... whatever.

Try to create a loop between a LAN port and the WAN/Internet port - do both the LAN and the Internet LED lit?

* Christian_R the LED description on p.11

===

Internet LED: Solid white. The Internet connection is ready.
Blinking white. The port is sending or receiving traffic.
Off. No Ethernet cable is connected between the router and the modem.
===

Complete unclear if the Internet LED indicates an Ethernet link (similar to the LAN ports) _or_ a working Internet connection.

What-if a user will see an amber Internet LED? Hmmmmmm. When we continue on p.107, we find that the Internet LED can be white or amber - no word about above:

===
In the Traffic Control section, specify whether the router should issue a warning
message before the monthly limit of Mbytes or hours is reached.
By default, the value is 0 and no warning message is issued. You can select one of
the following to occur when the limit is attained:
• The Internet LED blinks white or amber.
• The Internet connection is disconnected and disabled.
===

Now, what is the amber here? One could assume that this happens if connecting a slower (10Mbit/s or 100Mbit/s) WAN connection _or_ it's indicating some kind of problem/error.

The new documentation (and the implementation on the router) isn't great at all.

Hello cas434 - I'd like to see if we can get support to reach out to you. If you'd like to be contacted by support, please send me a message with your contact info.

I am currently waiting for support to call me but I did some troubleshooting in the mean time.

I bridged the internet port and a LAN port by plugging an ethernet cord between them and the internet port began blinking amber so the port itself is not defective from the looks of it. There is just something going on between my modem and the AX8. 

I am at a lost since I can leave the modem disconnected from battery backup and power for 20 minutes and then plug it in to the AX8 and it won't detect the cable. But I can immediately plug the modem back into my old router and it will immediately reconnect to the internet.

I have the same problem. My old router works with the verizon fiber modem, but the ax8 does not...

What is that modem?

Did you resolve your issue?

Seems not. Do you see a "Solved" tag. Unfortunately, people have a habit of throwing questions in and then vanishing.

Have you tried the various suggestions already made in this discussion?
