Hi Ganesh Pavan Reddy Y,
Welcome to Microsoft Q&A forum. I'm happy to help.
Please turn off your laptop and hold the power button for at least 10 seconds to re-initiate devices, your laptop might recognize the wireless card again.
- Enter your BIOS to check if your wireless card / Bluetooth device / WLAN device appears on device list.
- Check Device Manager again to see if Bluetooth and WLAN appear, or you might have unknown device if you did not install drivers yet.
If you can see your wireless card but don't have the drivers, please provide your laptop model so I can help you find the right drivers for your system.
If you have any further information, please feel free to let me know.
