There are many reasons for this and here are some solutions:

1. Check the Wifi on/off button on your laptop

This may be you accidentally or someone else pressed the Wifi connection off button on your laptop. The solution now is that you just need to turn the Wifi detector back on. Each laptop line will have a different way to turn it on, usually we will use the key combination Fn + F1,2.9. For example:

- For Asus or Dell computers it will be: Fn+F2
- For Lenovo computers it will be: Fn+F5

You observe if there is any yellow exclamation mark icon. If there is, it means that the wifi driver is not installed.

Next, you need to reinstall the Wifi Driver. There are many ways here, you can download the Driver from the manufacturer's homepage or use automatic Driver installation software such as DriverEasy for example.

4. Computer infected with Virus

Viruses are also one of the reasons why computers cannot connect to Wifi. The cause of virus infection here may be because you use Crack software or do not have anti-virus software to protect. So the solution now is that you need to install a reputable anti-virus software and remove viruses as well as malicious applications. To find effective anti-virus software, you can refer to the article Top best anti-virus software 2017 that we have shared.

5. Error due to antivirus software blocking wifi network

If you are using anti-virus software, it is very possible that this anti-virus software has taken control of network information, causing it to accidentally conflict with the wifi network you are using, so turn off the network censorship feature of the anti-virus software.

Here is an example of you are using AVG antivirus software. To turn off network censorship, do the following:

First, open Network and Sharing Center => go to Change Adapter Settings . Next, right-click on Local Area Connection and uncheck AVG network Filter driver and click OK .
