The WiFi Serial Transceiver Module w/ ESP8266 is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. It is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your Arduino device and get about as much WiFi-ability as a WiFi Shield offers. It is an extremely cost effective board with a huge, and ever growing, community.

Finally got it connection to WIFI

The default baud rate is set to 115200 for AT firmware. But was able to change to 9600 using arduino UNO and connected to WIFI.
