Wired Ethernet line to pc is running at 100mbps instead of 1gb
I just connected my pc via ethernet cable (Cat5e) to the nighthawk r7000. It blinks red and is running at 100mbps, instead of 1 gb. The troubleshooting steps I have already done are as follows. ...

Okay so I purchased a ethernet cable tester, turns out the cable was indeed bad. I went ahead and created a new cable, and it does have a gigabit connection.
Lesson learned dont trust your laptops lan port, try more than on device, and most likely it is the cable.

I tried to look for one but didn't see anywhere that I could change the speeds.

I remember of a past posting that a 10/100mb lan had problems with the a netgear's 1gb port they could only get a very low speed on that lan feed. It was a older lan card the poster had but the 1 gb switch fixed the issue I can see a possible that new and old want to fight the switch seem to stop them. I understand that a gb lan port on a older computer should be the same standard as today but some how they do not also see eye to eye and go to war.

The NIC card that is on the motherboard is only 3 years old tops.

If you have another ethernet cable, then I suggest you try that. Though I suspect it will behave the same way (based on the other tests you've run) it's still worth a try.

If you see a setting for "energy efficient ethernet" (or similar wording) try turning it off, and see if there is any difference.

Okay so I have found it
It is a intel r I218-V adapter
It is under advanced
I found 2 interesting things one is gigabit master slave mode, which is set to auto detect. And Speed and duplex which is set to auto negoitaite
I do not know what that first one is but ill try chaning the second one and see if anything happens

I don't think it'll matter, but the manual setting for "gigabit master slave mode" would be slave. If it makes no difference, set it back to auto-detect.
