Can't connect using wired ethernet connection

[Wajath_Shaik]

Hi, since this morning I've been unable to connect using my ethernet connection.

things I've done since:

• check network adapters -> the Ethernet adapter is missing
• check device manager -> LAN is missing
• download and install the latest LAN driver from official HP support, -> doesn't do anything when I try to set up
• restart and boot to diagnostics(f2) and tried testing the wired component -> got an error  "UEFI Networking does not appear to be supported or enabled on the system. Please check the BIOS settings to ensure that the UEFI network option ROMs are enabled and that the UEFI network boot is enabled."
• restart and boot to BIOS (f10) -> Advanced tab is missing, no way to enable/disable UEFI network option ROMs but I was able to enable the UEFI network boot
• restart and boot to diagnostics(f2) and tried testing the wired component -> still the same error
• restart and boot to bios(f10) and load default values -> UEFI network boot got disabled again
• restart and boot to diagnostics(f2) and tried testing the wired component -> still the same error
• check network adapters -> still missing
• check device manager -> still missing
• tried to install the latest LAN driver -> still not working
• tried replacing the Ethernet PCB board from OEM HP -> still missing
• tried replacing the motherboard from OEM HP -> still missing
  If anyone can help me out, please reach me at contact.wajath@**bleep**.com

Hi @Wajath_Shaik,

Welcome to HP Support Community.
 

Thank you for posting your query, I will be glad to help you.

"I understand you're having trouble connecting your PC to Ethernet, and the drivers are either not being detected or unable to sync. I’m sorry to hear about the issue—I know how frustrating that can be. Let’s go through some troubleshooting steps to resolve this. Please follow the steps below, and let me know how it goes!"

Let's try a basic set of steps on the PC before we can try any other steps.

BIOS Restore:
1) Shutdown the computer, keep the  charger plugged

2) Hold down the Windows and B button together while the computer is still turned off.  

3) Turn on the computer and continue to hold the Windows and B button until a BIOS Recovery screen appears.  

4) Follow on-screen instructions and click on OK

I hope this helps.

Take care and have a good day.
