R8000 LAN ports 1 and 2 will not go to 1000mb speeds but 3 and 4 will
Hi, have just bought a secondhand nighthawk X6 R8000, having a really strange issue where LAN ports 1 and 2 will not go to 1000mb speeds, staying at 100mb(orange light) 3 and 4 are working perfect, i can plug a cable into 3 will be at 1000mb then plug into 1 and will drop to 100mb then back to 3 and be at 1000mb, i have updated the firmware and did 2 factory resets. all cables that i am using are CAT6 and going into gigabit ports, Only thing i have noticed is the power suppy is 12v and through looking it should be 17v would this make a difference, just wondering before i buy a new power supply to try,

"looking" at what? The R8000 User Manual says:
Power adapter All regions (output): 19V/3.16A DC output
What's printed on the device (label) itself?
> [...] would this make a difference, [...]
I would not be amazed by some kind(s) of problem(s) appearing as the power-supply voltage dropped from nominal towards zero. Predicting the exact symptoms and thresholds is beyond my abilities. 12V is enough less than 19V that I'd want to run the experiment with a proper power supply.
But it's also possible to fry an Ethernet port. Or damage a connector, so that a gigabit/s port can't see all eight conductors, which would be needed for gigabit/s speed.

Sorry meant 19v. was looking at the back of router. Really thinking it could be the power supply. Was thinking that the pins could have lost contact as well tho. It's strange one

The good news is that Netgear's power adapters are generic. It doesn't sell them, but any adapter will work, as long as it has the right volts, enough amps and a tip with the right (+/-) polarity and dimensions.
You may have one lying around somewhere. Some on-line emporia even tout their adapters as being compatible with particular Netgear models.
Another hidden "feature" is that Netgear's devices may say 120 V on them, but some of us have taken our life on your hands and plugged them into 240 volts. (Detached from the router of course.) No nasty bangs and broken adapters.

Should be cheaper than replacing the R8000. I wouldn't issue a life insurance policy on ports 3 and 4, but they could last longer than some other critical part, too.
