Connecting to network with wifi shield

Question

I just bought a WiFi shield and I cannot connect to my wireless network (WPA2).

• I used the sketch from the Arduino site for connecting to WPA network and put my SSID and password on but it doesn't connect (I know the credentials are correct as I used my phone to connect with these WiFi credentials).
• When I read the serial monitor it just keeps trying to connect. The WiFi-shield board error light is red
• I checked my network settings and my block level is at is lowest (NAT only).

Why can't I connect?

Answer 1

In the loop:

// attempt to connect to Wifi network:
 while ( status != WL_CONNECTED) { 
 Serial.print("Attempting to connect to WPA SSID: ");
 Serial.println(ssid);
 // Connect to WPA/WPA2 network: 
 status = WiFi.begin(ssid, pass);
 // wait 10 seconds for connection:
 delay(10000);
 }

Can you add Serial.print(status); before the delay so you can see if any of these arise:

• WL_IDLE_STATUS = 0
• WL_NO_SSID_AVAIL
• WL_CONNECT_FAILED
• WL_CONNECTION_LOST
• WL_DISCONNECTED

They are defined in wl_definitions.h

Answer 2

I was facing the same issue using the Feather M0 board from Adafruit. After updating the Arduino IDE as well as the IDE's libraries and firmware, I was able to connect to WiFi.
