Hello Achowdhury and welcome to community,

The issue is there due to some virtual driver.

Please try the following the solution.

Kindly go to Network and Sharing Centre then Change adapter settings and delete the Incoming Connection if any

Restart the system and check, if the issue persist then uninstall the wireless lan driver from device manager and

Right Click on my computer--> Manage-->Local Users and groups-->Groups--> in right panel Double Click Users
- Remove all NT_AUTHORITY

After this scan for hardware changes and install the driver. Also look if there is any virtual driver in network adapter category in device manager and if find disable it.

Please try these steps and let us know the result.

Best Regards,

Tanuj
