Wierd Issue causing MDNS Fail and hardware watchdog reset in wifi connection #1

There is a weird Issue causing MDNS Fail and hardware watchdog reset in wifi connection. This issue seems to be resolved after removing wifi.persistent(false); I don't know how it is related, but somehow, this seems to solve the problem. We'll investigate later.

removing this isn't wise, because it'll lead to behaviors like - even if we removed a wifi from the settings, it'll still connect to the same network.

Another things that seems to be working is this - 

        WiFi.mode(WIFI_OFF);
        delay(200);
        // See https://github.com/esp8266/Arduino/issues/2186
        if (strncmp_P(ESP.getSdkVersion(), PSTR("1.5.3"), 5) == 0) {
            WiFi.mode(WIFI_OFF);
        }

        WiFi.enableSTA(true);
        WiFi.hostname(_hostname);

Note that we have to call wifi.mode(WIFI_OFF) because otherwise it'll start in AP+STA Mode.

We can also disable the wifi.persistent(false); But then in our main function setup() we'll have to call wifi.disconnect() before starting.
