Hi nischur,
I will recommend you to run the diagnostics on your system to check the hardware functionality:
- Restart your system and keep tapping 'F12' as soon as the Dell logo appears.
- Highlight 'Diagnostics' using up/down arrow keys and press enter.
Please let me know if you get an error code/message.
Also, are you facing any wireless issues with your system? Please share the wireless card your system has.
Keep me posted. Please reply for any further questions.
