Tests performed

The following tests are performed:

• Save and restore a WiFi profile.
• Restore a WiFi profile when no profile has been saved previously.
• Generate an Access Point using the default configuration.
• Generate an Access Point using a saved profile.
• Change the WiFi device to Station mode (mode necessary to connect to other access point).
• Change the WiFi device to access point mode (mode necessary to generate an access point).
