Arduino with ESP8266

I have completed the circuit and code to interface ESP8266 module with Arduino UNO.

When i send AT,AT+RST from serial monitor the reply is correct .

But when i send AT commands to search WIFI networks (AT+CWLAP) & connect to WIFI (AT+CWJAP="SSID","password") the reply is ERROR.

But the IP address (may be default) is obtained as 192.168.4.1 when i send AT+CIFSR .

I am really struggling with this issue. Could you please help me ?
