Computer Fails to Detect Integrated Network Adapter on H81M-S2H Motherboard Despite Driver Updates

Hello, is there anyone able to help or direct what and how?

Well, I do not know what the fault may be. When I connect the internet cable to the integrated network card of the motherboard (H81M-S2H), the device manager does not detect this card, there are no question marks, and when I click to connect me to the internet then solve the problems, I get a message that no network card has been detected. I installed mobo drivers both from the disc and from the manufacturer's website, I did the format but nothing works. The LEDs on the back of the Internet cable input are off.

In the task manager, under "show hidden devices" there is only what is in the attachment, except that TP- link wireless usb adapter is a wireless network card that I am currently sitting on.

Hello,
what are your bios settings? maybe you have the card turned off.
best regards

I have an uefi bios and I don't really know where it is so honest (layman).

As you can see, this function is enabled and the cards are still not detected

Download and run linux live from cd / pendrive, does it detect the card under linux?

what if it doesn't detect?

Card damaged on the board.

installed, how to check the network card there?

Connect the cable and check if there is internet, start the terminal and in the terminal

ifconfig
ping -c 6 8.8.8.8
lspci

paste results for the "spoiler" section

I just have something like that, that's it?

Before these commands in the termial window, run

sudo su -

and then the rest

ifconfig
ping -c 6 8.8.8.8
lspci


It looks like the network card is showing "Ethernet controller"

As I wrote, I have already done the format and did not give anything.

tp link adapter works for rectification, the integrated network card from mobo does not work

Don't kick this horse, buy a pci card for 15 PLN on Allegro and forget about the problem.

You can try to upload the chipset headsets again, make sure the headsets match the model and version of the motherboard.

I think I will, but I wanted to fix the problem without spending money.
The point is that I installed everything from the mobo board + I also tried to install from their website, but nothing works ...

Boot your entire computer with a Linux flash drive or CD, not VirtualBox, and then check again. VirtualBox emulates all hardware so obviously it will show a working ethernet controller.
