Arduino snippet for simplifying WiFi connection

[ghost]

Got this snippet from Alex, makes code transparent with respect to password protected and non-password protected WiFi networks. We can update Arduino WiFi-examples to use this:

// Connect to Wifi network.
while (status != WL_CONNECTED) 
{
    Serial.print("Attempting to connect to SSID: ");
    Serial.println(ssid);

    if (strlen(pass) > 0)
    {
        status = WiFi.begin(ssid, pass);
    }
    else
    {
        status = WiFi.begin(ssid);
    }

    // Wait for connection.
    delay(5000);
}
