NODE MSU + WiFi network

Hello. I can not connect the NODE MSU module to the WiFi network. In this case, the Port Monitor displays squares. What can be wrong? Perhaps something with Wihdows encoding or is it an IDE 1.8.9 curve? Node MSU seems to be working. Any ideas? Thanks.

Node MSU? Did you mean NodeMCU? If not, please post a clickable link.

And by Port Monitor you mean Serial Monitor? Squares appearing implies the Baud rate is not set to match your sketch.

You say that the "Node MSU" is not connecting to Wifi but also it is working correctly. Please clarify.
