I can not see the Arduino serial monitor the IP it receives from the router. I just get the message .scandone
No SSID found, reconnect after 1s
Wifi evt: 1
STA disconnect: 201
.reconnect

My router uses WPA2 encryption. How can I solve this problem?

@Marcelphilippeandrade you are not calling initWifi() anywhere, which is the function that actually calls WiFi.begin().
Closing due to user error.
