#include <WiFi.h>
char ssid[] = "yourNetwork"; // the name of your network
int status = WL_IDLE_STATUS; // the Wifi radio's status
void setup() {
// initialize serial:
Serial.begin(9600);
// attempt to connect to an open network:
Serial.println("Attempting to connect to open network...");
status = WiFi.begin(ssid);
// if you're not connected, stop here:
if ( status != WL_CONNECTED) {
Serial.println("Couldn't get a wifi connection");
while(true);
}
// if you are connected :
else {
Serial.print("Connected to the network");
}
}
void loop() {
// do nothing
}
But then Serial Monitor said there were no networks available, when my computer is currently connected to my university wifi and I have a cellular hotspot I could connect to. Any troubleshooting ideas?

The serial monitor is displaying "no networks can be found" and "no wifi connection" after I run the code.
I also want to have a free-standing prototype. After I connect the wifi does it have to stay plugged into the computer or after the information is inputted in the code it will be able to connect?

use the Ethernet library, not the WiFi library.
there is nothing wireless on that shield.
you can connect it to WiFi network only with a WiFi bridge
