Can you explain what "my network name" is?

Hello.
This is the name of my wifi device (esp32)

@Robin2's serial basics topic should get you started.
Why is the password a uint32_t, and not a string?

Don't forget to stop and restart the wi-fi.

Your Arduino definitely can't handle RS232 signal levels; you will need a converter for that. Modern PCs don't have RS232 ports; you can use a USB to RS232 converter.

But maybe you just meant serial.

Robin's Serial Input Basics - updated might possibly give you some ideas for serial communication.

You probably have something in your code like char *networName = "HelloWorld". In which case you have to be careful.

Exactly, the name is just that in this format.

So, you need to find the maximum length of an SSID, and size your name array appropriately.
Don't forget to allow space for the string terminator.
