@anne_droid​ it's my all details of laptop solve the problem 

@UttamBhunia​  couldn't show any WiFi option 

Hi

I was rather hoping for a Dell model number etc etc.

Since it looks like you have BlueTooth and they are normally on the same adapter, it suggests a software error with your Wi-Fi.

So if you can tell more about it the better the help will be.

Hi

The attached file 0toF.txt should be renamed 0toF.bat, and then run, posting what you can back.

If in doubt please ask.

Hi

So the ping to 127.0.0.1 was successful, which means....

Working TCP/IP stack: A reply confirms that your operating system's networking software is installed and running correctly.

With no Wireless interface being "present", you may need to replace it.

You didn't post the getmac to see if there are MAC addresses for wifi, bluetooth and ethernet.

The results of these two may have helped...

ipconfig /all
msinfo32

Therefore in the absence of of further/better info, I suggest you visit a local Dell repairer.

If in doubt please ask.

Hi

I think you are either using a VPN and/or Virtualisation.

You are telling me nothing about your networking to enable me to give a sensible suggestion.

Take it to a local repair shop and have them fixit for you.

I wish you luck.

BYE.
