Driver Problems: Outdated, corrupted, or missing drivers can cause network connectivity issues. Network Configuration Issues: Incorrect IP settings or network settings might prevent proper communication. Hardware Problems: The Ethernet cable or the network port might be faulty. Operating System Issues: OS-related settings or updates might conflict with the network connection. Firewall or Antivirus Interference: Firewalls or antivirus software may block network access.

Detailed Troubleshooting and Solutions

Step 1: Check Physical Connections

Before jumping into software-based fixes, ensure that:

The Ethernet cable is securely connected to both your computer and router/modem. Try using a different Ethernet cable if possible, as the current one may be damaged. Test the Ethernet port on your computer by plugging into a different port or another device to verify it’s working. Step 2: Verify Network Status Open the Network Connections window: On Windows, press Windows + R, type ncpa.cpl, and press Enter. Locate the Ethernet adapter (RTL8152B-VB-CG), right-click it, and check the status. If the status says "Disabled," right-click and select Enable. If it says "Connected" but there's no internet access, proceed to the next step. Step 3: Update or Reinstall the RTL8152B-VB-CG Ethernet Adapter Driver Update Driver: Right-click the Start button and select Device Manager. Expand the Network adapters section, right-click the RTL8152B-VB-CG Ethernet Adapter, and select Update driver. Choose Search automatically for updated driver software. Windows will search for and install any available driver updates. Reinstall Driver (if updating doesn’t help): Right-click the RTL8152B-VB-CG Ethernet Adapter in Device Manager and select Uninstall device. Once uninstalled, restart your computer. Windows should automatically reinstall the correct driver upon reboot. Step 4: Release and Renew Your IP Address

Sometimes, the issue lies with the IP configuration. Here’s how to reset it:

Open the Command Prompt as Administrator. Press Windows + X, then select Command Prompt (Admin) or Windows Power Shell (Admin). Type the following commands and press Enter after each one: ipconfig /release – This will release the current IP address. ipconfig /renew – This will request a new IP address from your router. Once the process is completed, check if the network access is restored. Step 5: Reset TCP/IP Stack

If the problem persists, reset the TCP/IP stack to resolve any potential network configuration issues.

Open the Command Prompt as Administrator. Type the following command: netsh int ip reset Restart your computer to apply the changes. Step 6: Check for Conflicts with Antivirus or Firewall

Sometimes, antivirus software or a firewall can block network access. To check:

Temporarily disable your antivirus or firewall software and check if network access is restored. If disabling the antivirus/firewall resolves the issue, you may need to adjust the settings or switch to a different antivirus program. Step 7: Test the Ethernet Adapter on Another Computer

To check whether the issue is with the Ethernet adapter or your computer:

Plug the RTL8152B-VB-CG Ethernet adapter into another computer. If the adapter works correctly on the second computer, the issue might be with your computer's hardware or settings. Step 8: Reset Your Network Settings (as a Last Resort)

As a last resort, you can reset your network settings to default:

Open Settings (press Windows + I), and go to Network & Internet. Under the Status tab, scroll down and click on Network reset. Click Reset now, and restart your computer. This will remove all network adapters and reinstall them, which might resolve any deep network configuration issues.
