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.
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.

I tried to look for one but didn't see anywhere that I could change the speeds.
Try selecting the adapter in the windows device manager. With Intel NICs there often is a "Speed & Duplex" settings included in the "advanced" tab of the NIC properties.
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.
Instead of auto setting, manually set speed at 1Gb, duplex. Then see. In the device manager can you see manufacturer of the NIC card.
Even tho Windows says latest driver, you can check the manufacturer site to see if there is latest driver.
I manually set duplex mode to the 1gb option. The computer did not even detect the ethernet cable pluged in. Tried power cyceling both pc and router still nothing, so switched it back to auto.
So I went on intels site, there is a new driver. I downloaded it, and unziped it. Then instal wizard ran. Went through the whole proccess. It completed. Then checked back on device manager, and ethernet port still has same driver from last time.
On the driver: try rebooting the PC.
Overall: The common denominator in the testing is the PC, everything else seems to be working at 1 gigabit.
I'm thinking this is most likely a marginal connection in the PC NIC port or possibly the cable. Putting a gigabit switch between the router and the PC might work around the problem.
