user45764: I try to connect my NodeMCU Amica to my WiFi network, but it doesn't detect any networks around. I chose Board "NodeMCU 1.0 (ESP - 12E Module)", upload speed of 115200 and I have the correct port selected.
When I try the blink sketch, it works perfectly, but when I try to use the WiFiScan example, I only get the message "no networks found" and I don't. 
I did pay attention that the upload speed in the sketch and monitor are always the same as the one I selected. Also, I tried out different upload speeds, without any succes either.
I already changed my network to 2.4 GHz, and also tried to downgrade the libraries to older versions, but nothing helped till now.
About any help, I would be really glad.

user45795: Firstly try to set it up as AP and check whether is it working ? If not, there is issue with power supply. Because WiFi Scan requires more current... than normal WiFi connection operation.
