Hi sashikanth,

Welcome to the Dell Community. In order to get your issue fixed, I would suggest you to turn off the device and turn it on and see if Wi-Fi works. If you are still facing issue, try resetting your device to factory defaults. You can visit the following web link for step by step instructions to reset the device to factory defaults.

Note: Resetting device to factory defaults will erase personal data. You can follow instructions in the following web link in order to backup your personal data.
