Realtek LAN driver issue after Windows 10 22H2 update

[Martha9666]

I updated windows to 22H2 version, and after that I have in device manager an error near Realtek Gaming GbE Family controller device (LAN adapter). And it does not work, does not display in network devices. 
I installed LAN drivers from HP official website for my laptop model, hovewer it did not affect the situation. On the official support page there are no drivers for Win 22H2 version for my laptop. 
Nod in the device manager I see the warning "The driver for this device has been blocked from starting because it is known to have problems with Windows. Contact the hardware vendor for a new driver. (Code 48)"
Manual driver install, searching for a driver through windows update center does not make any result.
How to make my LAN adapter work again?

Hi @Martha9666,

Welcome to HP Support Community.

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

When facing an issue like the one you're experiencing with the Realtek LAN driver after updating to Windows 10 version 22H2, and encountering the "Code 48" error, there are several steps you can take to attempt to resolve the issue. Since you've already tried updating the driver from the HP official website and through Windows Update without success, let's explore some alternative solutions:

1. Roll Back the Driver

If the issue started after an update, rolling back the driver to a previous version can sometimes resolve the problem.

• Go to Device Manager, find your Realtek Gaming GbE Family Controller under Network Adapters, right-click it, and select Properties.
• Go to the Driver tab and see if the Roll Back Driver option is available. If it is, click it and follow the prompts.

2. Uninstall and Reinstall the Driver

Uninstalling the driver completely and then reinstalling it can sometimes clear up the issues caused by corrupt or incompatible drivers.

• In Device Manager, right-click on the Realtek Gaming GbE Family Controller and select Uninstall device. Make sure to check the box to delete the driver software for the device if prompted.
• After uninstalling, restart your computer. Windows will attempt to reinstall the driver upon reboot. Alternatively, reinstall the driver manually using the installation package you downloaded from HP's website.

3. Use Compatibility Mode for Driver Installation

If HP provides a driver but specifies it's for an earlier version of Windows, you can try installing the driver in compatibility mode.

• Right-click the driver installation file and select Properties.
• Go to the Compatibility tab, check the box for Run this program in compatibility mode for, and select the Windows version the driver was originally intended for.
• Run the installer as administrator by right-clicking it and selecting Run as administrator.

4. Disable Driver Signature Enforcement

Sometimes, driver signature enforcement can prevent drivers from installing properly. Disabling it temporarily might allow the installation to proceed.

• Access the Advanced Boot Menu by restarting your computer and pressing F8 (or Shift + F8) during boot.
• Choose Disable Driver Signature Enforcement from the list of startup options.
• Once Windows starts, try installing the driver again.

5. Check for Windows Updates

Although you've already tried this, it's worth checking for Windows updates periodically, as Microsoft often releases fixes for known issues.

I hope this helps.

Take care and have a good day.
