Arduino mega and ESP8266 project

Projects General Guidance

Hello! i am working on a project here but i am having a little problem. I try to connect the Arduino Mega using the esp8266 to internet. the code is shown below:

#include <SoftwareSerial.h>

SoftwareSerial wifi (2, 3); //Rx, Tx

void setup() {
Serial.begin(115200);
Serial.println("Wifi Started");
wifi.begin(115200);
}

void loop() {
if (Serial.available() > 0) {
byte b = Serial.read(); wifi.write(b);
}
if (wifi.available() > 0) {
byte b = wifi.read(); Serial.write(b);
}
}

After uploading, i try the at command in the serial monitor but nothing shows up. The connection is as follows:

rx --> pin 2 (with voltage divider)
tx --> pin 3
gnd --> gnd
ch_pd,vcc --> 3.3v
GPIO0 --> gnd

I dont my think my esp8266 is working with my Arduino Mega. Im not really sure. Any help will be appreciated. Thanks!

GPIO0 connected to GND boots up your ESP8266 in program mode. So it's waiting for you to upload software, and won't respond to AT commands. Disconnect GPIO0 and let it float (or pull it up to Vcc) for normal boot.
