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...

"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.
As usual, many things are possible.
- 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

It's strange oneThe 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.
Soooo got a correct powersupply, 19v, still having the same issue LAN ports 1 and 2 stay at 100m, 3 and 4 at 1000m,
only thing that i have noticed is that when i plug in to 1 or 2 there is a long delay in the light coming on compared to 3 and 4,
Tried a firmware downgrade and another reset just incase,
Next options is just to plug in an unmanged 8 port switch to get a round this missing ports
