About the Wi-Fi

I have checked that if I add a network, and this network does not broadcast the SSID, I write the SSID and the password and I always receive the same message: Connection failed to XXXXXXX.

I have a second network on an access point that does broadcast the SSID and on that one I have no problem connecting to it.
I don't know if it is a problem with my network or something attributable to the GPS.
If anyone else can try and publish the result I would appreciate it.

Greetings
