If you have ever worked on esp8266 arduino library you probably have faced this issue.
sometimes, you wrote your new SSID for your ESP8266 like below in your code
WiFi.softAP("MySSID-HomeAutomation", "1234") // wifi ssid name and password
But it’s not showing in your wifi search. You must be seeing something like below, vendor specific name. or your old esp8266 wifi ssid name.
This is because, You might had set the wifi SSIDd or Password name too small,
You have to rewrite your password minimum 8 Characters Long.
