Hello Mike, thank you for your reply.
What do you mean for "turned off and then turned on"? Could it be done automatically by Windows? It is strange because we try to start the wifi more times and every time it doesn't work.
Considering this kind of error, do you think we can try with another class, to create this wifi connection?
We used also the normal netsh command to create an hosted network, but it doesn't work (probably because this is not supported by Windows 10 and by this wifi dongle).
Thanks again for the help.
