Should I not use the "Stealth SSID" that hides the Wi-Fi name?

Distinguished name of Wi-Fi access point "SSID (Service Set Identifier)". If you set it on a device such as a Wi-Fi router, the character string set as the SSID will be broadcast all at once, and it will be possible for devices within the communication range to recognize it as a connection target. Simply put, the SSID is the name of a Wi-Fi router, which is a marker for PCs and smartphones to try to connect.

Stealth SSID does not improve security The SSID can be "hidden" in the device settings (Stealth SSID). Hiding it works just by not including the SSID when a device such as a Wi-Fi router broadcasts. It is the same except that the SSID is not sent, so it does not improve security. Moreover, the stealth SSID can be found. Some network analysis software for personal computers has a function to find out stealth SSID, and if you use it, you can effectively disable stealth. The effects of stealth SSIDs can also backfire. For example, let's say you're using a laptop with your home Wi-Fi router as a stealth SSID. If you take the laptop out of the house with Wi-Fi enabled and use it at a cafe or train station platform ... the laptop will continue to broadcast the SSID of your home Wi-Fi router in an attempt to reconnect (probe). request). Since the communication of the device that knows the SSID and tries to connect to the access point includes the SSID, it becomes a notebook PC that repeatedly calls the SSID of the Wi-Fi router at home outside the home. Stealth SSID has the advantage that you do not have to know the name of your Wi-Fi router in the neighborhood, but it is not a security measure, and if you feel like it, a third party can check the SSID. It will be. You should think that it's better not to hide the Wi-Fi name, rather than it's ineffective.
