[Q] It seems difficult to connect to Wi-Fi...

[A] Easy connection using WPS

Communication using radio waves via Wi-Fi has the great advantage of eliminating the need for cables. There is a problem that if the radio waves used for communication are intercepted, the content of the communication will be tapped. Therefore, in Wi-Fi, eavesdropping is prevented by encrypting the communication contents.

The "key" for this encryption is the password set for the access point. To connect to the Internet using Wi-Fi on a PC, smartphone, etc., you must enter the password set for the access point correctly.

However, it is also true that the presence of this password is a factor that makes Wi-Fi connection difficult.

That's where "WPS (Wi-Fi Protected Setup)" comes in, a mechanism that makes it easy to connect to Wi-Fi.

In the case of Windows 10, you can connect with WPS by clicking the [Internet Access] button in the task tray and pressing the button on the access point side on the screen after selecting the access point. For connection, you can connect to Wi-Fi without entering a password by pressing the access point button or entering a 4- or 8-digit number.

To use WPS, both the access point and the terminal connected to the network via Wi-Fi must support WPS.

In addition to being supported by many access points made by Buffalo, NEC Platforms, and IO Data Devices, it can also be used with Windows 10. However, iOS used in iPhones and iPads and Android 10/9 do not support WPS.

In addition, the position and name of the button on the access point side varies depending on the product, so check the instruction manual.
