Hi! @ROCKETERIA, Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community!

 

I understand you have issues connecting your PC using the ethernet connection.

 

Don't worry I'd like to help you out.

 

Did you make any hardware or software changes on your PC?

 

As you mentioned you are unable to find the ethernet driver listed in device manager.

 

Do you see any exclamation mark in device manager?

 

Try the steps recommended below.

 

Manually change network settings

 

Manually changing the network settings can resolve wireless connection issues. Create a restore point in Windows, and then manually change the network settings.
Using the search box on the taskbar, search for and open Create a restore point.
The System Properties window displays.
Click Create.
Type a name for the restore point, and then click Create.
Windows creates the restore point.
Using the search box on the taskbar, search for Command Prompt. In the results list, right-click Command Prompt, and then click Run as administrator.
If a User Account Control screen displays asking if you want to allow the app to make changes to your computer, click Yes.

Type the following commands one at a time, pressing Enter after each one.
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=enabled
To open the TCP Global Settings, type netsh int tcp show global in Command Prompt and then press Enter.
Make sure all settings are disabled except Receive-Side Scaling State.
Close Command Prompt, reboot the system and then try to connect to the Internet.

 

Also, try updating the latest drivers using HP support assistant.

 

Refer this article to know more information about using HP support assistant.

 

If the issue still persists after trying out the steps.

 

It is a hardware issue with your PC. Please contact HP support for service options.

Let me know if this works! 

Have a great day! 🙂

@CF4, It's great to hear from you again.

 

I appreciate your efforts for trying out the steps.

 

As you mentioned the ethernet driver is not getting listed device manager.

 

Do you see light glowing next to the ethernet port?

 

I do see Realtek PCIe family controller listed in device manager.

 

Which means the ethernet card on your PC functioning correctly.

 

Try checking with a different ethernet cable and check if it helps.

 

Also, try the steps recommended below.

 

1. Launch the Settings.
2. Go to the Network & Internet menu.
3. On the Status tab, scroll down for Network Reset.
4. Click the Reset now button.
5. Click Yes and restart the PC.

 

After the PC restarts try updating the drivers using HP recovery manager.

 

Refer this article to know how to restore drivers using HP recovery manager.

 

 

I'll watch your reply!

Have a great day ahead! 🙂

I don't have a problem. You might, but I definitely don't.
