Network card driver

Solved

Hello,
First of all, I don't know if I'm in the right place on the forum and secondly, I want to say that I'm not very good with computers.
BEFORE a storm, I turned off my box, which I hadn't done in a long time. When I turned it back on, everything was normal except that my PC no longer has internet access. The laptops in the house are fine.
The Windows network diagnostic tells me: "Windows has not detected a properly installed network card. If you have a network card, you need to reinstall the drivers."
When I go to Network Properties, it says: Maximum Transmission Unit: 0
Connectivity (IPv4/IPv6): Disconnected

I went to Control Panel - Network and Sharing Center - then Set up a new network connection: and the response is "Windows has detected no network hardware."
I also updated the 8 drivers of the card in the Device Manager.
I'm running Windows 10.
I don't know what to do anymore. If you can help me, I sincerely thank you.

Hello,
You are not precise enough:
Is your PC a laptop or a desktop?
Is your PC connected via WiFi or Ethernet?
Was it plugged into the wall during the storm?
If connected via Ethernet, was the phone line unplugged during the storm?
Go to Device Manager and tell me if any device has an error (yellow triangle), and check and tell me what is in Network Adapters.

Hello Bazfile,
Sorry for my lack of clarity
my computer is a desktop connected via Ethernet. My computer wasn't plugged into the mains during the storm because it was connected to a power strip that was turned off, like the box. However, the phone line was not unplugged, but I still have access to the phone and the connection for the laptops works without any issues;
In the device manager, there is no yellow triangle.
In network adapters:
Wan Miniport (IKEv2)
Wan Miniport (IP)
Wan Miniport (IPv6)
Wan Miniport (Network Monitor)
Wan Miniport (PPPOE)
Wan Miniport (PPTP)
Wan Miniport (SSTP)

Your network card is dead and needs to be replaced. When there's a thunderstorm, always unplug the phone line. Buy a PCI network card or a USB WiFi adapter; these are just examples, there are plenty of other models.

Oh no. We often have severe storms in the South and I've never unplugged the phone. Thank you for your quick response and I will look into the solutions to implement.

The box being also connected to the phone socket, when there are storms, you need to unplug the power plug of the box and the phone socket; otherwise, it follows through to the Ethernet socket connected to your PC's network card. You are lucky because it could have also fried your motherboard and your box. This year, there have been many burnt network cards due to the storms that were very numerous at the beginning of summer.
Have a good day.
