Thanks for your assistance Chuck. Here is your Connect_wifi example with my parameters:

#include <WiFi.h> // Use this for WiFi instead of Ethernet.h
#include <MySQL_Connection.h>
#include <MySQL_Cursor.h>


byte mac_addr[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

IPAddress server_addr (192,168,2,43); // this is the IP address of my PC with MySQL on it. I initially tried 127,0,0,1 but that always failed to connect.
char user[] = "LP"; // MySQL user login username
char password[] = "mypassword"; // MySQL user login password
char ssid[] = "BELL148"; // your SSID
char pass[] = "mywifipassward"; // your SSID Password

WiFiClient client; // Use this for WiFi instead of EthernetClient
MySQL_Connection conn((Client *)&client);
//MySQL_Cursor cur = MySQL_Cursor(&conn);

void setup() {
Serial.begin(115200);
while (!Serial); // wait for serial port to connect. Needed for Leonardo only

// Begin WiFi section
int status = WiFi.begin(ssid, pass);
if ( status != WL_CONNECTED) {
Serial.println("Couldn't get a wifi connection");
while(true);
}
// print out info about the connection:
else {
Serial.println("Connected to network");
IPAddress ip = WiFi.localIP();
Serial.print("My IP address is: ");
Serial.println(ip);
}
// End WiFi section

Serial.println("Connecting...");
if (conn.connect(server_addr, 3306, user, password)) {
delay(1000);
}
else
Serial.println("Connection failed.");
conn.close();
}

void loop() {
}

I'm running MySQL V8.0.16. The user "LP" has Standard authentication. I discovered that MySQL is logging Aborted Connections with this error:
IP address '192.168.2.56' could not be resolved: No such host is known.
This is the IP address my router assigns the Realtek board.

On the MySQL Workbench it shows the connection for 10 seconds or so, but the user and host are "None".
