Many people have several Wi-Fi access points in their homes and workplaces.Many of the commercially available Wi-Fi routers divide the access points for each frequency band (2.4GHz band and 5GHz band), and when using Wi-Fi, you have to choose one.
The iPhone has a function to automatically connect to Wi-Fi access points and is processed based on the previous settings.For example, when access points A and B that have been connected are nearby, if you connect to A the last time A, and if you connect to A, and B, try to recreate to B.If you can't connect, you'll try to connect to the other access point, so the user can use Wi-Fi without being aware of it.
However, since the 2.4GHz band and the 5GHz band (and wireless communication standards that use each frequency band) have different connections and communication speeds, they may want to use B instead of access point A.prize.There are also characteristics for each frequency band that the 2.4GHz band reaches the distance to the distance, and the 5GHz band is less susceptible to other electronic devices than the 2.4GHz band, so the need to choose according to the situation.There will be some.
In response, iOS 13 was devised in the control center.Press and hold the area at the top left of the screen and press the Wi-Fi button when the six buttons are displayed.Then, the surrounding Wi-Fi access points are listed, and you can start the connection by tapping.Compared to iOS 12, which had no choice but to launch the "Settings" app and display the "Wi-Fi" screen, the switching work should have been easier.
