Hi Nisha G,
Welcome to Microsoft Q&A forum. I'm happy to help.
Please provide more information about the issue you're having so I can better understand and assist you:
- Did you install necessary drivers for your laptop, especially Wi-Fi driver from your laptop support page or application?
- When you connect to a Wi-Fi, what happen? Do you receive any error messages?
- Do other devices connect to that Wi-Fi normally?
- Did you try to connect to another Wi-Fi?
Thank you for your time.
