Ethernet won't work. HELP!

[Nicolas]

My PC is not able to connect to the internet since yesterday, it is connected to the router through ethernet, it is able to see other devices in the network, wifi works fine, and I can connect other devices through ethernet to that same router and they also work fine, but not my PC.

 

I have already done:

 

- Restarted router

- Restarted PC

- Disabled and enabled network controller

- Flushed DNS

- ipconfig looks normal

- Reinstalled network drivers

- Bought an ethernet to USB adapter to use a different network adapter (which I have confirmed works on other devices)

 

All that to no avail.

 

It is an older PC (about 10 years old) running windows 10 so I suspect there could be some faulty hardware somewhere, but if I don't find any more solutions I might do a fresh windows install to see if that works, maybe it is finally time to upgrade to windows 11.

Reset network settings fully: Run this in Command Prompt as admin:
netsh int ip reset
Then restart the PC.

Set a static IP: Go into network adapter settings and manually assign an IP in the same range as the router (e.g., if router is 192.168.1.1, set 192.168.1.50).

Turn off firewall and antivirus temporarily.

Start Windows in Safe Mode with Networking: If internet works there, a background program or driver is causing the problem.

Boot from a Linux USB: If it connects there, the hardware is okay and Windows is the issue.

If nothing works, reinstall Windows or upgrade to Windows 11. This will reset everything and often fixes deep connection issues.

Will try all of that. Thank you!
