esp8266 AND cipserver command: HELP!

Hi guys,
I am working with my ESP8266 and I using simple AT commands in order to get used with it. I have a big problem: when I set a TCP server on port 80, I can't reach it opening firefox or other browser. When I write 192.168.1.4 in firefox URL I have this:

ready
AT

OK
WIFI DISCONNECT
WIFI CONNECTED
WIFI GOT IP
AT+CWMODE=1

OK
AT+CIFSR

+CIFSR:STAIP,"192.168.1.4"
+CIFSR:STAMAC,"18:fe:34:da:88:8b"

OK
AT+CIPMUX=1

OK
AT+CIPSERVER=1,80

OK
AT+PING="192.168.1.1"

+4

OK
AT+PING="192.168.1.8"

+114

OK
AT+PING="192.168.1.8"

+3

OK
0,CONNECT

0,CLOSED

0,CLOSED appears after some minutes and I think because the browser can't connect to my esp8266.
As you can see I can't receive "ok" from my ESP8266 so I can't use CIPSEND command in order to display something on web page! As you can see from my code, ping command works well and If I ping 192.168.1.4 from my pc, the operation is good too! So,what's the problem? I am following this guide:WiFi Module ESP8266 – 2. TCP CLIENT /Server mode | alselectro
I am using arduino board and arduino software for serial communication.
Thank you

your connection got closed because it is idle.

There is no OK for IPD, it tells you how many bytes to read, in your case, you read 314 bytes after the : character. Then you can start your cipsend to reply.

if you do not want to timeout the connection, set at+cipsto=0
