ESP8266-01 with arduino Mega disconnect when router restart

Solved

I got it :blush::blush::blush::blush::blush::blush::grinning:.
To let any ESP8266 work automatically if any wifi issues will happen we have to update the BlynkSimpleShieldEsp8266.h library as following:
1- add #include <avr/wdt.h> library inside the BlynkSimpleShieldEsp8266.h library.
2- add wdt_enable(WDTO_1S); and wdt_reset(); to connectWiFi lines as shown down:

 bool connectWiFi(const char* ssid, const char* pass)
    {
        ::delay(500);
        BLYNK_LOG2(BLYNK_F("Connecting to "), ssid);
        /*if (!wifi->restart()) {
            BLYNK_LOG1(BLYNK_F("Failed to restart"));
            return false;
        }*/
        if (!wifi->kick()) {
             BLYNK_LOG1(BLYNK_F("ESP is not responding"));
			wdt_enable(WDTO_1S);
                        wdt_reset();
             //TODO: BLYNK_LOG_TROUBLE(BLYNK_F("esp8266-not-responding"));
             return false;
        }
        if (!wifi->setEcho(0)) {
            BLYNK_LOG1(BLYNK_F("Failed to disable Echo"));
            return false;
        }
        String ver = wifi->ESP8266::getVersion();
        BLYNK_LOG1(ver);
        if (!wifi->enableMUX()) {
            BLYNK_LOG1(BLYNK_F("Failed to enable MUX"));
        }
        if (!wifi->setOprToStation()) {
            BLYNK_LOG1(BLYNK_F("Failed to set STA mode"));
            return false;
        }
        if (wifi->joinAP(ssid, pass)) {
            String my_ip = wifi->getLocalIP();
            BLYNK_LOG1(my_ip);
        } else {
            BLYNK_LOG1(BLYNK_F("Failed to connect WiFi"));
			wdt_enable(WDTO_1S);
			wdt_reset();
            return false;
        }
