It won't print into my serial port. But if I remove "WiFiClient client;" from the begining of my scketch, it works OK (If I remove every reference to "client").

I think ESP8266WiFi.h should replace WiFiClient.h when using the ESP8266. I don't think you should use both.

I didn't realize that those libraries are ambiguous.. Thank you for that.

Looks like the problem isn't with Wifi libraries... I just noticed these warnings:

Any advice?
