i can t connect my raspberry pi zero w 2 to my wifi

The first time i flashed the OS in my micro sd card using raspberry image, i flashed the Raspberry Pi OS(32-bit) becouse im using the v2 camera, and i changed the defoult settings, i enabled the shh and the wifi setting the name and the password(I checked it, it's correct and my wifi is 2.4ghz and 5ghz), then i put my micro sd in the raspberry but it doesn't connect. The second time i flashed the OS in the same way but i didn't modify the settings and i just added the ssh file(without exentions)and the file for the information of wifi, i insert IT(Im from italy), my wife name and password(the file was conf) and also this second time didn't work. The third time i used etcher for flashing directly the OS in my micro sd card and i added shh file and the conf file, but also this third time it didn't work. All three times i connect my raspberry to my laptop using my micro-usb cable and i waited for the booting and all the three times i formatted the micro sd card can someone help me please???

connect a monitor and keyboard to the pi
