Many users encounter this problem when the update interferes with the proper functioning of network Drivers . This guide will walk you through the possible causes and provide clear, step-by-step solutions to fix the issue.

Possible Causes:

Driver Incompatibility: After a Windows update, the existing Drivers might be incompatible with the latest version of Windows, causing the RTL8152B-VB-CG adapter to stop working. Corrupted or Missing Drivers: Windows updates sometimes corrupt or remove necessary drivers, leading to malfunctioning network adapters. Power Management Settings: The update might have altered power settings that are causing the USB device to disconnect or fail to be recognized. Conflicting Software: Certain third-party software or Windows security settings might conflict with the adapter after an update.

Solutions to Fix RTL8152B-VB-CG Adapter Issues:

Step 1: Check Device Manager for Driver Issues Right-click the Start menu and select Device Manager. Scroll down to Network adapters and expand the section. Look for the RTL8152B-VB-CG adapter. If there’s a yellow triangle or exclamation mark next to it, this indicates a driver issue. Right-click on the adapter and select Update driver. Choose Search automatically for updated driver software. Windows will attempt to find and install the latest driver. If no driver is found, go to the Realtek website and download the latest drivers for your specific adapter model. Step 2: Roll Back Driver (if available)

If the driver was working fine before the update but stopped afterward, you can try rolling back to the previous version.

In Device Manager, right-click your RTL8152B-VB-CG adapter and select Properties. Click the Driver tab and select Roll Back Driver (if the option is available). Follow the on-screen instructions and restart your computer. Step 3: Uninstall and Reinstall the Network Adapter In Device Manager, right-click the RTL8152B-VB-CG adapter and choose Uninstall device. Restart your computer. Upon reboot, Windows should automatically detect the adapter and reinstall the necessary drivers. Step 4: Disable Windows Power Management for the Adapter

Windows might be putting the network adapter into a low-power state, causing it to stop working.

In Device Manager, right-click the RTL8152B-VB-CG adapter and select Properties. Go to the Power Management tab. Uncheck the option that says Allow the computer to turn off this device to save power. Click OK and restart your computer. Step 5: Disable USB Selective Suspend

Sometimes, the USB Selective Suspend feature can cause issues with USB Ethernet adapters.

Open the Control Panel and go to Power Options. Click on Change plan settings next to your active power plan. Click Change advanced power settings. In the Power Options dialog, expand USB settings and then USB selective suspend setting. Set it to Disabled and click Apply. Restart your computer. Step 6: Check for Windows Updates

It’s possible that there’s a newer update that can fix the issue. Here’s how to check:

Open Settings from the Start menu. Go to Update & Security and select Windows Update. Click Check for updates. If updates are available, install them and restart your computer. Step 7: Manually Install the Realtek Driver

If Windows updates and automatic driver updates didn’t help, you may need to install the driver manually.

Visit the Realtek website and download the most recent driver for the RTL8152B-VB-CG. Once downloaded, run the setup file to install the driver. After installation, restart your computer and check if the adapter works. Step 8: Test the Adapter on Another Computer

If possible, try using the RTL8152B-VB-CG adapter on another computer to determine if the problem lies with the adapter itself or with your system configuration.

Conclusion:

The RTL8152B-VB-CG adapter issue after a Windows update is typically caused by driver incompatibility, corrupted drivers, or changes in power settings. By following these troubleshooting steps, you should be able to resolve the issue and get your Ethernet adapter working again. If none of these solutions work, contacting Realtek support or seeking help from a technician may be necessary.
