Ethernet - Not Connected

Hello!

About 3 days ago, my desktop randomly stopped recognizing my Ethernet connection. At first, I thought it could be my cable or motherboard, so I cleaned up my desktop and replugged everything. I tried using the same cable on my Nintendo Switch and it worked.

I didn't know what else to do, so I tried reinstalling the drivers, but it still shows "Ethernet - Not Connected." I bought a new cable, plugged it in, and it still didn't work. Then, I bought a USB-to-Ethernet adapter to test my USB ports, and that didn't work either.

I don't know what else I can do, so I found this forum hoping for some help.

I have already tested:

1. Replugging the cable
2. Cleaning the computer
3. Trying another cable
4. Trying an adapter
5. Running some DISM/SFC commands (still running while writing this post)

What else can I try?

Thanks!

Hello @imdj and welcome to ElevenForum.


It could be, the actual Ethernet port on the motherboard (rear).
I guess it could have something to do with the router.

Look over this Link: Fix Ethernet connection problems in Windows | Microsoft Support

EDIT:
make sure the latest available motherboard drivers are installed,
downloaded directly from the board manufacturer's product support page(s).

check your Device Manager for any 'Network adapter' or other warnings.

if all else fails, it could very well be that your motherboard has just malfunctioned.
you could try a network PCIe card with Ethernet available

You need to examine the Ethernet Plugs cables and sockets for functionality, all of them.

Plugs - Test for springiness of the retaining tab, use a Multimeter (resistance) to ascertain any intermittent plug/cable both ends.
Sockets - make sure the springy finger contacts are lined up and separated correctly and are still springy.

Examine contacts for corrosion, clean contacts with alcohol. General mechanical examination for worn/broken parts.
