When connected to WiFi, there is a time limit (this time is set in the router), and after it expires, the usage time is re-obtained.

Configuration of the WiFi network, including security settings, etc.

A description of the WiFi wireless connection, including access point, network connection status, hidden access point, IP address, connection speed, MAC address, network ID, signal strength, and other information. Here's a quick rundown of how to do it:

getbssid() to get bssid

getDetailedStateOf() to get the client's connectivity.

gethiddenssid() to get if the ssid is hidden.

getipaddress() to get the IP address.

getlinkspeed() to get the speed of the connection.

getmacaddress() to get the mac address.

getrssi() to get the signal of the network.

getssid() to get the ssid

getsupplicanstate() returns information about the specific client state.

Needless to say, this is used to manage our wifi connection, and some classes have been defined here for us to use.
