Hello!

I accidentally uninstalled my ethernet driver, so I reinstalled it, but now the PC doesn't detect the cable... However, the Wi-Fi is still working.

I've tried everything: resetting the PC, uninstalling the driver, etc. I don't know what to do anymore. If you have any ideas, please let me know!

Here are 2 screenshots of my components and driver ( https://imgur.com/a/Zkb0q ), the ethernet driver is this one: Realtek PCIe GBE Family Controller.
As you can see, I have no errors...

I'm waiting for your replies, hoping for a solution :)
Thanks!

ok,
you just need to check if your Ethernet port works well by booting from a live CD or live USB Linux, like Ubuntu for instance, without installing it, unless you prefer otherwise, just to test.
If it works well under Ubuntu, you will need to consider reinstalling Windows, since you don't have a restore point.

  So, I don't know much about PCs, so to get started like you told me, I imagine it's in the BIOS but I would need some guidance.
  
  And as mentioned in my question, I've already done a Windows reset.

    What do you mean by a Windows reset then?
    As for a live USB Ubuntu, we discussed that in a recent conversation, I'll look for it.

    Describe what you did to "reset your PC," because there are several methods.
    Just to make sure we understand ;-)

Hello,

Thanks to the people who advised me.
I finally managed to solve my problem. I struggled with it for a month over a cable issue... Indeed, I just unplugged and replugged all the cables of my PC and it was good.

    It would be better if he told us which cable was making a poor connection, but we will assume it was the network cable.

Good evening,

Go to your device manager and give me the identification number of your network card.
By the way, let me know if you have a yellow triangle in front.

  Good evening,
  
  For the device manager, there is no triangle as shown in the screenshots above, and here is the identification number:
  
  PCI\VEN_10EC&DEV_8168&SUBSYS_861D1043&REV_11
  
  Thank you.

  Try installing this driver:

  Oh okay :-)
  
  Have you uninstalled the driver and run the automatic search in Windows 10 for your card?
  
  If there are no results, try the detection on this site and see if it finds another driver for you:

  What do you mean by "Did you uninstall the driver and run the automatic search of Windows 10 for your card?"
  If it’s about uninstalling the driver and restarting the PC for the driver to reinstall automatically, that's already done :p
  
  And for driverscloud, it finds the same driver.

You gave me your device manager.
But I’m asking you this:

And while you're at it right-click on Ethernet connection and right-click properties __ configure __ power management __ uncheck allow this computer to turn off this device.

  Plug in the Ethernet, then right-click on the Ethernet connection and try a diagnosis.
  
  Yes, we need to find an element that would guide us toward the issue :-)

  The Ethernet is connected, but when I run the diagnostics, it tells me that no cable is plugged in or that it is damaged. However, the cable works well; I tested it on other devices.
  
  Thank you :)

  It doesn't help us...
  I don't really know anymore...
  
  Try this latest driver from Realtek for Windows 10:
  Win10 Auto Installation Program (SharedID:1152921504607039569 SId:1152921504626192484)
  On this page:
  http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false
  
  Unzip and run AutoInst.

Weird ...

If you go to Network and Internet --- Network connections
What does it say about Ethernet?

Do you remember what exactly you uninstalled?

Also,

  Have you tried another cable?
  Another Ethernet socket on your box?
  Is it flashing on your box at the Ethernet port?
  
  (I'm out of stock here, but I hope reinforcements will come soon ;-) )

  The Ethernet port means that it is the motherboard if it's a laptop.
