Red light appears when TV is connected into a Nighthawk AC4000 (R8000P) LAN port

What does it mean when a front LAN indicator light is red? Our Nighthawk AC4000 is brand new. We plugged in an LG 65" OLED TV into a LAN port (#4) using a CAT-7 Ethernet cable. The #4 front indicator LED immediately turned red. The LG's settings show that both the wired and wireless services are connected to the internet. Unfortunately, the fastest internet service we can buy is 15Mbps. Is that the cause of the red indicator?

   If only there were some kind of documentation for your router which
described its LED indicators and what they mean.  But wait!!!

   Visit http://netgear.com/support , put in your model number, and look
for Documentation.  Get the User Manual (at least).  Read.  Look for the
LED descriptions.

   Is your "red" what Netgear calls "amber"?

   A TV does not need gigabit/s speed to do its job.

   No, that's strictly a LAN Ethernet question; it's independent of the
speed of your Internet service.  But it ought to be clear that if your
Internet connection speed is much less than 100Mb/s, then LAN speeds of
100Mb/s and 1000Mb/s should be pretty tough to distinguish.  Neither
would be where your bottleneck lies.

I had consulted the User Manal, but all I saw about LED colors was "white" and "amber." And everybody I showed the light to called it "red." So I assumed that the red light meant there was some sort of a problem with the TV, the cable, or the router that was not addressed in the Manual.

Thanks again for your input!
