Try this snippet:

SYSTEM_MODE(SEMI_AUTOMATIC);

uint8_t retry_count = 0;
unsigned long old_time = millis();

void setup(){
    WiFi.on();
}

void loop(){
     if(millis() - old_time >= 2000){        
        if(retry_count < 10){
            if(!WiFi.ready()){
                WiFi.connect();
                retry_count++;

            }
            else if (!Spark.connected()){
                Spark.connect();
                retry_count++;
            }
        }
        else{
            WiFi.off();
            retry_count = 0;
            WiFi.on();
        }
        old_time = millis();
    }
