Can't get IP from serial monitor | WeMos D1 R2

Development Tools IDE 1.x
1

Hello.
I tried to use wemos d1 r2 and uploaded WiFiWebBrowser example. But the ssid does not appear on my laptop and when i run serial monitor on my arduino IDE, it just give me infinity point. So what should i do?

#include <ESP8266WiFi.h>

const char* ssid = "your-ssid";
const char* password = "your-password";

// Create an instance of the server
// specify the port to listen on as an argument
WiFiServer server(80);

void setup() {
  Serial.begin(115200);
  delay(10);

  // prepare GPIO2
  pinMode(2, OUTPUT);
  digitalWrite(2, 0);
  
  // Connect to WiFi network
  Serial.println();
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);
  
  WiFi.begin(ssid, password);
  
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.println("WiFi connected");
  
  // Start the server
  server.begin();
  Serial.println("Server started");

  // Print the IP address
  Serial.println(WiFi.localIP());
}

void loop() {
  // Check if a client has connected
  WiFiClient client = server.available();
  if (!client) {
    return;
  }
  
  // Wait until the client sends some data
  Serial.println("new client");
  while(!client.available()){
    delay(1);
  }
  
  // Read the first line of the request
  String req = client.readStringUntil('\r');
  Serial.println(req);
  client.flush();
  
  // Match the request
  int val;
  if (req.indexOf("/gpio/0") != -1)
    val = 0;
  else if (req.indexOf("/gpio/1") != -1)
    val = 1;
  else {
    Serial.println("invalid request");
    client.stop();
    return;
  }

  // Set GPIO2 according to the request
  digitalWrite(2, val);
  
  client.flush();

  // Prepare the response
  String s = "HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n<!DOCTYPE HTML>\r\n<html>\r\nGPIO is now ";
  s += (val)?"high":"low";
  s += "</html>\n";

  // Send the response to the client
  client.print(s);
  delay(1);
  Serial.println("Client disonnected");

  // The client will actually be disconnected 
  // when the function returns and 'client' object is detroyed
}

in this case i used WeMos D1 R2 esp2866.
Wifi ssid didn't appear, once it appear but can't be connected and serial monitor can't show the ip address or it can't be connected.

This seems very similar to your other thread:

ZaqyW:

WiF iSe rve r server(80 ); //Initialize the server on Port 80

void setup() {
WiFi.mode(WI FI _ AP); //Our ESP8266-12E is an AccessPoint
WiFi.softAP("Hell o_ IoT ", "12345678 "); // Provide the (SSID, password); .
server.be gi n (); // Start the HTTP Server

Why do you have all these extra spaces in the code?

Use code tags (</> button on the toolbar) when you post code or error messages, not quote tags.

i'm sorry for my bad.

#include <ESP8266WiFi.h>
WiFiServer server(80 ); //Initialize the server on Port 80
void setup() { 
WiFi.mode(WIFI_AP); //Our ESP8266-12E is an AccessPoint
WiFi.softAP("Hello_IoT ", "aaaaaaaa"); // Provide the (SSID, password); . 
server.begin (); // Start the HTTP Server
Serial.begin(115200);
IPAddress HTTPS_ServerIP = WiFi.softAPIP();
Serial.print("Server IP is: ");
Serial.println(HTTPS_ServerIP);
}
void loop(){}
