Hello @ashoksaini123 ,

Welcome to our community.

Since the adapter shows no light and isn't being detected, let's try the following troubleshooting steps before considering a replacement:

1. Unplug the adapter from your PC and plug it back in firmly.

2. Try different USB ports on your computer • test both USB 2.0 and USB 3.0 ports if available.

3. Go to Computer Management > Device Manager > Action > Scan for hardware changes, and check if it shows up in Network Adapters/Other Devices/Universal Serial Bus controllers.

4. If your PC has a built-in wireless adapter, disable it in Device Manager to ensure there's no conflict.

5. (Optional) Go to Device Manager > Universal Serial Bus Controller > USB Root Hub and double-click it, then go to Properties > Power Management > uncheck "Allow the computer to turn off this device to save power". Save and restart the computer after modifying the properties of each USB Root Hub.

6. If possible, test the adapter on another computer to help determine if it's a hardware failure with the adapter itself.
 

If the adapter still shows no light and isn't detected after these steps, please contact local support for further suggestions.
