Connecting arduino nano 33 iot to wifi

Hi, I have a problem dealing with Arduino Nano 33 IoT. I tried to connect the Arduino Nano 33 IoT to my wifi but then, it some sort like unstable. I already tried scan my networks and my wifi totally stabled. I'm not sure why, I tried to solve the problem in a month but still I could not find a way. Plus, I already used VUSB of Arduino Nano 33 Iot for supplying voltage of 5V to my sensors. Is it related to firmware update or the VUSB itself. The code that I implemented is shown below:

#include <SPI.h>
#include <WiFiNINA.h>

char ssid = "xxxxxx";
char pass = "xxxxxxxx";

int status = WL_IDLE_STATUS;

WiFiSSLClient client;

void connectToAP(){

while ( status != WL_CONNECTED){
Serial.print("Attempting to connect to SSID: ");

status = WiFi.begin(ssid, pass);



void printWifiStatus(){

Serial.print("SSID: ");

IPAddress ip = WiFi.localIP();
Serial.print("IP Address: ");

void setup() {
// put your setup code here, to run once:

while (!Serial){
if (WiFi.status() == WL_NO_MODULE){
Serial.println("Wifi module failed!");


void loop() {
// put your main code here, to run repeatedly:


00:58:47.261 -> Attempting to connect to SSID: xxxxxx
00:58:51.628 -> Connected...
00:58:51.628 -> Attempting to connect to SSID: xxxxxx
00:59:00.543 -> Connected...
00:59:00.543 -> Attempting to connect to SSID: xxxxxx
00:59:04.485 -> Connected...

I mean, if the controller successfully connected, the serial monitor should show the IP Address.
