LAPTOP UNABLE TO CONNECT TO WIFI ALL OF A SUDDEN !

My laptop has been connected to wifi for more than a year.
A few days ago it was unable to do so. It identifies the wifi connection and the signal strength is termed ' excellent '.
The other devices at home are able to connect to wifi as usual.
So the problem is some setting in my laptop. I have tried troubleshooting.Nothing works.
Could some setting in the registry be the cause?

Some help would be really appreciated.

Hi arcprasad,

 

Thank you for posting your query in the Microsoft Communities. From the problem description I understand that you are not able to connect to the WiFi network. Provide the following information for the better understanding of the issue:

 

·         Have you made any changes on the computer prior to the issue?

·         Do you get any error message?

·         Are you using any third party security software?

·         What troubleshooting steps did you try?

 

Follow these methods.

 

Method 1: Disable the security software temporarily.

 

Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you are connected to the Internet or a network during the time your antivirus software is disabled, your computer is vulnerable to attacks.

 

Method 2: Follow the steps:

 

Step 1: Boot the computer in safe mode with networking and check if the issue persists.

 

Advanced startup options (including safe mode)

 

Step 2: If the issue does not persist in safe mode with networking, perform a Clean Boot  to see if there is any software conflict as clean boot helps to eliminate software conflicts.

 

Note: After performing the troubleshooting steps in clean boot, follow Step 7 from the link to start the computer to Normal startup mode.

 

Method 3: Follow the steps from the article.
