Why Your RTL8153B-VB-CG Network Connection Keeps Disconnecting and How to Fix It

If you are experiencing network disconnection issues with your RTL8153B-VB-CG USB to Ethernet adapter, there are several reasons this might be happening. This article will break down the possible causes of this problem, why it happens, and how you can fix it with easy-to-follow solutions.

1. Check the Hardware Connection

Before diving into software-related issues, ensure that the adapter and cables are securely connected. A loose or damaged USB connection can cause disconnections. Here’s how to check:

Step 1: Unplug the adapter and inspect the USB cable for any visible damage or wear. Step 2: Reconnect the USB cable firmly to both the Ethernet adapter and the USB port on your computer. Step 3: If using a USB hub, try connecting directly to the computer’s USB port to rule out any issues with the hub.

2. Update Device Drivers

Outdated or corrupted drivers can lead to network connectivity issues. Updating your drivers is often the first and easiest solution.

Step 1: Press Win + X on your keyboard and select Device Manager. Step 2: In the Device Manager, find Network Adapters and locate your RTL8153B-VB-CG device. Step 3: Right-click on the device and select Update Driver. Step 4: Choose Search automatically for updated driver software. Step 5: If an update is found, install it and restart your computer.

Note: If the automatic update doesn’t solve the issue, you can also visit the manufacturer’s website to download the latest driver version and install it manually.

3. Adjust Power Settings

Sometimes, the computer’s power management settings can cause network adapters to power off or disconnect automatically. Disabling USB selective suspend can help resolve these issues.

Step 1: Press Win + X and select Power Options. Step 2: Click on Additional power settings on the left side. Step 3: Choose Change plan settings next to your selected power plan. Step 4: Click Change advanced power settings. Step 5: In the pop-up window, expand USB settings and then USB selective suspend setting. Step 6: Set it to Disabled and click Apply.

4. Check for Conflicting Software

Some software, especially third-party antivirus or firewall programs, may interfere with network connections. Try temporarily disabling any security software and check if the issue is resolved.

Step 1: Disable any active antivirus or firewall software on your computer. Step 2: Restart the computer and test the connection again. Step 3: If the disconnection stops, you may need to adjust the settings of your antivirus software to avoid conflicts.

5. Test with Different Devices or Ports

Sometimes the issue could be with the device you’re connecting to. If possible, try using the RTL8153B-VB-CG adapter on a different computer or using a different USB port on your current device.

Step 1: Test the adapter with another computer to see if the problem persists. Step 2: Alternatively, test using a different USB port on your current device.

6. Reinstall the Network Adapter

If none of the above solutions work, reinstalling the network adapter may help.

Step 1: Open Device Manager by pressing Win + X and selecting it. Step 2: Right-click on the RTL8153B-VB-CG device under Network Adapters and select Uninstall device. Step 3: Restart your computer. Windows will attempt to reinstall the necessary drivers automatically. Step 4: After the system restarts, check if the issue has been resolved.

7. Check for Windows Updates

Sometimes, system updates might contain fixes that address USB or network-related issues. Ensure that your Windows is up-to-date.

Step 1: Press Win + I to open Settings. Step 2: Go to Update & Security and click Check for updates. Step 3: If updates are available, install them and restart your computer.

8. Replace the Adapter

If none of the above solutions resolve the issue, there could be a hardware fault with the adapter itself. In this case, consider replacing the RTL8153B-VB-CG adapter. It might have suffered internal damage, and a replacement would be the best option.

Summary of Solutions:

Check your physical hardware connection. Update the device drivers. Adjust the power settings to disable USB selective suspend. Disable any conflicting software (e.g., antivirus or firewalls). Test with other devices or USB ports. Reinstall the network adapter. Make sure your system is up-to-date with Windows updates. Replace the adapter if all else fails.

By following these steps, you should be able to fix the disconnection issue with your RTL8153B-VB-CG network adapter and restore your stable network connection.
