If your PC can’t connect to the Internet, you’ll need to download a driver on a different PC and save it to a USB flash drive, so you can manually install the driver on your PC. You’ll need to know the PC manufacturer and model name or number.

 

Step8:-

 

Update the network adapter driver

Sometimes antivirus or malware-prevention software might prevent you from getting connected. You can see if the connection issue is caused by antivirus and malware-prevention software by turning it off temporarily and then trying to visit a website you trust..

If you’re not sure what antivirus or malware-prevention software program you have installed, Windows might be able to tell you.

    1.In the search box on the taskbar, type System and security, and then select Review your computer’s status and resolve issues.

    2.Select the down arrow next to Security.

Make sure you turn your antivirus or malware-prevention software back on as soon as you can to make sure your PC is better protected.

 

Step11:-

Step 12:-

Use network reset to reinstall network devices

 

Using network reset should be the last step you try. Consider using it if the steps above don’t help to get you connected. It removes any network adapters you have installed and the settings for them. After your PC restarts, any network adapters are reinstalled, and the settings for them are set to the defaults.

    1.Select the Start button, then select Settings  > Network & Internet  > Status > Network reset.

    2.On the Network reset screen, select Reset now > Yes to confirm.
