I am trying to use wifiMulti function to store multiple wifi credentials and connect to them. The question is there are a few wifi extender in my place. Therefore the ESP8266 will treat my router and 2 extenders as three different wifi signals even they have the same SSID and password. If I use wifiMulti.addAP() to add those SSID, it seems I add three sets of same SSID and password which does not make too much sense to me. Is there a way to resolve this issue? I am using esp-12 and the code is the example code for wifiMulti.
*************************************************************
#include <ESP8266WiFi.h>
#include <ESP8266WiFiMulti.h>

ESP8266WiFiMulti wifiMulti;

void setup() {
Serial.begin(115200);
delay(10);

WiFi.mode(WIFI_STA);
wifiMulti.addAP("ssid_from_AP_1", "your_password_for_AP_1");
wifiMulti.addAP("ssid_from_AP_2", "your_password_for_AP_2");
wifiMulti.addAP("ssid_from_AP_3", "your_password_for_AP_3");

Serial.println("Connecting Wifi...");
if (wifiMulti.run() == WL_CONNECTED) {
Serial.println("");
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
}
}

void loop() {
if (wifiMulti.run() != WL_CONNECTED) {
Serial.println("WiFi not connected!");
delay(1000);
}
}

You may have to manage the different devices yourself. Do a scan and find the different devices, their signal strength, the BSSID. Decide which you want to connect to based on the results.

Thanks. The BSSID is very useful when deal with different wifi signal with same SSID. The only annoy thing is I had to write a function to compare the signal strength as wifiMulti function doesn't have the ability to handle BSSID.
