Driver

As you know, any hardware requires software, which ensures stable operation. If the laptop does not detect WiFi, you should check the driver. Even if they are installed, it is recommended to update them.

The distance signal

So do not be surprised if the Internet suddenly disappeared, when you walked around the house or yard.

Mac address

There are situations when it can connect, but the router does not see Internet through my WiFi or stopped to see. When using the services of some providers, the user can not just change the network adapter because it changes the Mac address.

The Mac address is written on every router and user just need to call the operator to a new address to tie in with the old. You may be asked to dictate it completely, or to specify only the last few values of the entire room.

Antivirus or third-party programs

Third-party programs installed on the laptop may interfere with the driver or interfere with properly install the Internet connection that often happens when the device sees wifi but does not connect. In addition, sometimes anti-virus software interfere with the new connection. If possible, it is better to try first to connect to the Internet without a router. If all is well, then do not blame the program.

In addition to these, the reasons can be a lot. Basically, a variety of reasons develops because of problems with the operating system. So if nothing helps, try reinstalling your operating system. Perhaps all the problems go away.
