I just did a fresh install on a new rig I built. I installed the latest build of High Sierra with on it. I have a Asus Tuf Z270 Mark 1 motherboard with an I5 7600K and cannot figure out how to get the Ethernet up and running on it. Any advice would be appreciated and if i left anything out that would help you fix the problem just let me know!

Your motherboard has two different Intel LAN ports, Intel I211 and I219-V.

You can try to install through MultiBeast:
- MultiBeast > Drivers > Network > Intel > AppleIGB v5.3.5.3
The AppleIGB.kext is used for your Intel I211 LAN port, but can cause kernel panics.

- MultiBeast > Drivers > Network > Intel > IntelMausiEthernet v2.3.0
The IntelMausiEthernet.kext is used for your Intel I219-V LAN port and very stable.

If that doesn't work, try to install the kext manually :
Remove any previous failed attempts from /Library/Extensions and /System/Library/Extensions.

Open Finder and browse to /Library/Preferences/SystemConfiguration/ then delete these two files :
  • NetworkInterfaces.plist
  • preferences.plist
Download one or both AppleIGB and IntelMausiEthernet and put the kext(s) on your desktop.
Download and run KextBeast selecting /Library/Extensions as the location.

In Terminal :
Code:
sudo kextcache -i /
Press return, type your password (it will not show on screen), press return again and when the command has completed, restart.
 
Same problem, tried this @BreBo solution but it doesn't work..

That's because your motherboard has the Atheros Killer E2500 LAN port.

You can try to install through MultiBeast:
- MultiBeast > Drivers > Network > Atheros > AtherosE2200Ethernet v2.2.2

If that doesn't work, try to install the kext manually :
Remove any previous failed attempts from /Library/Extensions and /System/Library/Extensions.

Open Finder and browse to /Library/Preferences/SystemConfiguration/ then delete these two files :
  • NetworkInterfaces.plist
  • preferences.plist
Download AtherosE2200Ethernet and put the kext from the Release folder on your desktop.
Download and run KextBeast selecting /Library/Extensions as the location.

In Terminal :
Code:
sudo kextcache -i /
Press return, type your password (it will not show on screen), press return again and when the command has completed, restart.
 
I have a problem with ethernet on High Sierra.
Already using IntelMausiEthernet and the port is detected under system report.
I am using a Range Extender (TL-WA850RE) to provide an ethernet cable connection to my system. However, when I plug the ethernet cable, the system cannot obtain address from the Range Extender. It does not give address according to my router address, but giving random address instead (169.x.x.x). If i put DHCP manual address and DNS server, it says connected to internet, but I still cannot browse and ping to router address fail.

Is this a problem with my setting, or simply I cannot use Range Extender when plugging to ethernet port of Hackintosh (needs to use direct connection from router instead?)

Thanks for the help.

I am sorry, it might seems like, problem is on my Range Extender. I jump into conclusion before making further checking.

Will check and revert back here.

I had the same "no Ethernet after wake" and "no front panel USB 3" issue on my system. Used the IntelMausiEthernet.kext, installed via MultBeast per the above suggestion.

Note that I also had to manually REMOVE the old AppleIntelE1000e.kext from L/E before everything started to work.

Nice!
