Ethernet port probably dead

[JaimeF]

Hey forum,

Lately been having this frustrating issue with my ethernet port. For reference, it's a Asus Z170 Pro Gaming w/ latest BIOS and Windows 10 x64

 

It started happening a month or so ago maybe. I have an idea of what it could be but I just hope maybe theres something I've missed. A month ago was about when my old PSU started dying. Making cracking noise as if something was arching. I've had an ethernet port die due to a blown PSU before, so that only reinforces my concern.

 

It's detected in Device Manager, only I get

"This device cannot start. (Code 10)

{Operation Failed}
The requested operation was unsuccessful.

Reinstalling drivers and all associated software completely has been fruitless (As well as turning off automatic driver updates from Windows)

Resetting CMOS/Reflashing BIOS will cause it to work for 2 or so reboots. After that it goes straight back to giving me an error in device manager.

I've tested the port while it was working with my router and I can't fault it's operation before it stops working entirely.

When the port isn't working, I am still able to get a link between 2 devices, just nothing beyond that.

The fact that you can get it working though doesn't sound like a hardware issue to me. If I were you, I'd install a throwaway OS on the side just to see if it's Windows-related.

Windows 10 installs the drivers for you, you should not have to manually install them yourself.

I've let Windows install the drivers itself. I disabled that just so I could install them myself to see if the issue was there. I also forgot to mention that I've completely reinstalled Windows.

Try using Hiren's boot disc. Boot into mini xp and open up the browser. Basically it will install generic drivers. This should open up a browser window and you should be able to access the internet. If it does not work go out and get yourself a network card. If it does start you need to look into a software problem, be it the operating system it's self or a problem with installing the drivers. Make sure that you are using the proper drivers for Windows 10. It is extremely picky.
