yes I’ve seen that too 
you don’t have to reflash the wifi chip… these are lib errrors.
first I checked if this code worked, just to see the networks around you
WiFi scanner code - click
#include "AtWiFi.h"
void setup() {
Serial.begin(115200);
while(!Serial); // Wait for Serial to be ready
delay(1000);
// Set WiFi to station mode and disconnect from an AP if it was previously connected
WiFi.mode(WIFI_STA);
WiFi.disconnect();
delay(100);
Serial.println("Setup done");
}
void loop() {
Serial.println("scan start");
// WiFi.scanNetworks will return the number of networks found
int n = WiFi.scanNetworks();
Serial.println("scan done");
if (n == 0) {
Serial.println("no networks found");
} else {
Serial.print(n);
Serial.println(" networks found");
for (int i = 0; i < n; ++i) {
// Print SSID and RSSI for each network found
Serial.print(i + 1);
Serial.print(": ");
Serial.print(WiFi.SSID(i));
Serial.print(" (");
Serial.print(WiFi.RSSI(i));
Serial.print(")");
Serial.println((WiFi.encryptionType(i) == WIFI_AUTH_OPEN) ? " " : "*");
delay(10);
}
}
Serial.println("");
// Wait a bit before scanning again
delay(5000);
}
when uploaded to the WIO, just open IDE serial monitor.
You should see something like this
That means the wifi chip seems to work… part 2 follows for that you have to manual install 5/6 libs
