Why RTL8153-VC-CG Won't Detect Your Network and How to Fix It
The RTL8153-VC-CG is a popular USB-to-Ethernet adapter that many people rely on for network connectivity. However, at times, it may fail to detect your network, causing frustration. In this guide, we will explore the common reasons behind this issue and provide step-by-step instructions to resolve it in an easy-to-understand way.
Common Causes for the RTL8153-VC-CG Adapter Not Detecting the Network: Driver Issues Outdated or missing drivers are one of the primary reasons your adapter might fail to detect the network. Without the correct drivers, your computer can't properly communicate with the RTL8153-VC-CG adapter. Faulty USB Port or Cable A damaged USB port or faulty cable can prevent the adapter from connecting to your device properly, leading to network detection issues. Conflicts with Other Network Adapters If your computer has multiple network adapters, such as Wi-Fi and Ethernet, conflicts might occur. The system may prioritize another adapter over the RTL8153-VC-CG, causing the network detection failure. Power Management Settings Sometimes, your system's power-saving features may disable or limit the USB port where the RTL8153-VC-CG is connected, affecting its performance. Hardware Failure While rare, hardware failure within the RTL8153-VC-CG itself can prevent it from functioning properly. Step-by-Step Solutions to Fix the Issue: Update or Reinstall the Driver Go to the Device Manager on your computer (press Windows + X and select Device Manager). Find the "Network adapters" section and locate the RTL8153-VC-CG adapter. Right-click on it and select Update Driver. If Windows doesn't find an update automatically, you can go to the manufacturer's website (Realtek) to download the latest driver for the RTL8153-VC-CG. If updating doesn’t help, try uninstalling the driver and then reinstalling it. Check USB Port and Cable Disconnect the adapter from the current USB port and try connecting it to a different one, preferably on the back of your PC if you're using a desktop, as these ports often provide more stable connections. Check the cable for any visible damage. If it's worn or frayed, replace it with a new one. Disable Power Saving for USB Ports Open the Device Manager again. Expand the "Universal Serial Bus controllers" section and right-click on the USB Root Hub (you may have several). Select Properties, go to the Power Management tab, and uncheck the option that allows the computer to turn off the device to save power. Repeat this process for all USB Root Hubs listed. Check Network Adapter Conflicts In the Device Manager, make sure there are no conflicts with other network adapters. Right-click on each adapter and click Disable (except the RTL8153-VC-CG). Restart your computer to see if the network detection issue is resolved. Test the Adapter on Another Device If possible, test the RTL8153-VC-CG adapter on another computer or device. If it works there, the issue might be with your original system settings, drivers, or USB ports. If it doesn’t work on another device, the adapter itself might be faulty, and you may need to replace it. Reset TCP/IP StackSometimes, issues with network settings can prevent your adapter from detecting the network. To reset your TCP/IP stack: Open the Command Prompt as Administrator (right-click Start > Command Prompt (Admin)). Type the following command and press Enter:
netsh int ip reset Restart your computer and check if the issue is resolved. Final ThoughtsThe RTL8153-VC-CG network adapter may fail to detect your network due to various reasons, from software issues like outdated drivers to hardware problems. By following the steps outlined above, you can systematically identify the root cause and restore your network connection. If all else fails, contacting the manufacturer for further support or a replacement might be the next step.
