SOLVED - ESP8266 - Sketches Arduino -command relay

hi here,

I found an example and adapt it to command a relay. COde is fully fonctional (except sometime...)

My problems is that 3~5 consecutive time i can write or read the OUTPUT that command the relay.
Sometime Firefox has no response from the module during a long time.
I can see that the processor works well because char "." is printed from the loop() on the terminal but nothing regarding the WIFI communication.
I need to wait 3~4 minutes and ask again the IP adress of the WIFI module and I can have an answer from the module ESP8266.
Tested the module at several distances from my BOX -> same thing
Try to do action without activate relay ( prob of parasitics ...) -> no actions

Another test that i've done is to replace the ESP8266 module from Olimex with a cheap chinese module and now everything works well without loss of communication....
But the piece of wired are not beautiful on the EVB board !!!

Do you have any idea ?

Hello,

i've found what is my mistake !

I've changed the configuration of my BOX
Replaced WIFI BG and N by B+G only and everything works well.

I can command the Relay from the DEV CArd
