ESP8266 not connecting to WiFi
Maybe you have a space in your WIFI SSID so you should check this in your router. Also maybe your WIFI is on 5Ghz and the ESP can't see it because it is only for 2.4 Ghz. Also if your WIFI AP is on a channel from 13 - 14 it also couldn't be seen by the ESP. And to test your ESP you can run the scan example and if it works you should try the web server example to connect to your network. If that all will work ok than the problem is in your code.
