this morning noticed that, ethernet port isnt working,
last night it was working great, (SPECS : MOBO Z170 ASUS GAMING PRO CPU: i5 6600k),

there is no led showing back of the motherboard Ethernet port,
the weird thing is, i can see ethernet local area connection as "unplugged"
Screenshot (1).png

i tried to reinstall drivers too, didnt worked,
so buying expensive product even become crap?
why is it premium then,
is there any fix ?
or its dead

It got fried. Lightning is usually the cause.

You got to buy a network card.

Failures happen even on premium products. It happens, and will continue to, nothing is a guarantee.

You've verified with another Ethernet capable device that the cable(s) you were testing with are good?

I've seen recent Windows 10 updates kill the NIC/network stack, so rebuilding it might help. Try the following in an administrative command prompt session:
  • Type netsh winsock reset and press Enter.
  • Type netsh int ip reset and press Enter.
  • Type ipconfig /release and press Enter.
  • Type ipconfig /renew and press Enter.
  • Type ipconfig /flushdns and press Enter.
If that doesn't work try this:
  • netsh int ip reset c:\resettcpip.txt
    • c:\resettcpip.txt will log the results from the reset procedure.

Let us know if either of those help. :toast:

Try a different cable? Connectors do occasionally go bad (often with a lot of insertions and removals).

Have you changed ports on the other end (e.g. in your router)? If you have, I would either buy a USB3 -> 10/100/1000 NIC (great for testing) or a PCIe x1 NIC card (permanent fix assuming the onboard NIC is indeed dead).

I am absolutely going with Kursah here on the Network update. I've seen repeated issues with clients' computers not having network access/no connection due to a Windows 10 update.

There is always the possibility that the port has died. A recent storm may have caused a static pop in the line, just enough to cause the port to fail. Replacement PCIx network cards are cheap these days for replacement...

How to enable/disable lan fro motherboard?

You have to enter the bios setup and navigate to the "advanced" tab, then go to "Onboard Device Configuration" and see the "Intel Lan Controller"... it would be best to refer to the manual --> Asus Z170 Gaming Pro manual ( see pages 2-6 in section 2.2 on entering bios, pages 2-27 and 2-34 for advanced menu and lan info... in the English manual )

Try the "Network Troubleshooter" and "Network Reset" in Windows 10; if, by chance it was an update or such, it might clear the problem. .
The troubleshooter will probably tell you there is no connection or the cable is not connected... then, try the "Network Reset"

Troubleshooting network problems in Windows 10

To run the Network troubleshooter

  1. In the search box on the taskbar, type Network troubleshooter, and then select Identify and repair network problems from the list of results.
  2. Follow the steps in the troubleshooter and see if that fixes the problem.

Using network reset should be the last step you try. Consider using it if the steps above don’t help to get you connected.


This can help solve connection problems you might have after upgrading from a previous version of Windows to Windows 10, as well as fix problems where you can connect to the Internet but not to shared network drives. It removes any network adapters you have installed and the settings for them. After your PC restarts, any network adapters are reinstalled, and the settings for them are set to the defaults.


Note
To use network reset, your PC must be running Windows 10 Version 1607 or later. To see which version of Windows 10 your device is currently running, select the Start button, then select Settings > System > About.

  1. Select the Start button, then select Settings > Network & Internet > Status > Network reset.
  2. On the Network reset screen, select Reset now > Yes to confirm.
    Wait for your PC to restart and see if that fixes the problem.

Notes
After using network reset, you might need to reinstall and set up other networking software you might be using, such as VPN client software or virtual switches from Hyper‑V (if you're using that or other network virtualization software).
Network reset might set each one of your known network connections to a public network profile. In a public network profile, your PC is not discoverable to other PCs and devices on the network, which can help make your PC more secure. However, if your PC is part of a homegroup or used for file or printer sharing, you’ll need to make your PC discoverable again by setting it to use a private network profile. To do this, go to Settings > Network & Internet > Wi-Fi . On the Wi-Fi screen, select Manage known networks > the network connection you want to change > Properties. Under Network profile, select Private.

My bet is the adapter got fried. Mine got fried last week, actually exactly a week ago and it wasn't even due to lightning. The power went off and then immediately came back on, the power surge probably fried it.

Check was slots you have available on your motherboard. Hopefully you have one of the "x1PCI Express Slots" pictured here:


Here's a card that would work:
https://www.amazon.com/Rosewill-1000Mbps-Ethernet-supported-RC-411v3/dp/B004F34ONC/

Problem is, it doesn't come with Windows 10 drivers. You'll have to download them and transfer them to the machine by other means:
http://www.rosewill.com/product/ros...dapter-10-100-1000-mbps-pci-express-1-x-rj45/
0016-Install_Win10_10010_10212016.zip

Alternatively, should be able to use drivers from Realtek (likely more current):
