WeMOS ATmega 2560 esp8266 wifi R3找不到任何wifi网络

我有一个WeMOS ATmega 2560 esp8266 wifi R3，我想将传感器数据发送到thingpeak . 我刚刚开始使用它，并且无法找到wifi网络 .

我按照本指南：http://www.sysengineering.ru/blog/%D1%8D%D0%BB%D0%B5%D0%BA%D1%82%D1%80%D0%BE%D0%BD%D0%B8%D0%BA%D0%B0-%D0%BA%D0%BE%D0%BD%D1%82%D1%80%D0%BE%D0%BB%D0%BB%D0%B5%D1%80-arduino-mega-%D1%81-esp8266/

我'm able to connect to the at mega with no problems, get sensors data etc. But when I set my dip switches to 5,6,7 (for USB>ESP8266 mode), I can still upload, but my scan times out without detecting any wifi networks. I'能够与其他设备连接到那个wifi，它靠近所以应该很容易在范围内 . 我上传草图后，我将dip开关放到了只有5,6的RX0，但没有运气:(我已尝试过多个草图进行wifi扫描和连接，并且全部上传，但从未找到任何或连接 . 这是一个链接到我所拥有的确切董事会.https://www.amazon.co.uk/gp/product/B07HML8DZD/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

任何人都可以对我做错了吗？我只是想不出来 .

谢谢！

Picture of serial monitor after uploading sketch只是点是应该显示wifi连接 . 以下是我使用的代码示例：
