Buenas, estoy trasteando con un ESP32 para ver si consigo hacer que funciona de repetidor. Mi idea es que se renueven la señal unos a otros y así pueda tener ESP32 lejos de la antena emisora original. Funciona hasta cierto punto, se conecta y me emite la 2da red, tambien puedo conectarme con el pc a la red extendida, pero no me deja acceder a internet... Una ayudita?
