I need support about an interesting IP fenomenon.

I have two 4Duino display modul with ESP8266 from 4Dsystems. These two module are the same.
I testing them with one time with the same enviroment and code.
I use the atmega 32u4 micro to communicate with the esp through serial connection.
The system hardwarre is OK and both firmware is the same.

I use AT commands in the code.
The only one problem now what I encountered is the following.
One of these two module is correctly connecting the router with the expected IP address but the other module is every time connecting with 0.0.0.0 IP.

Would you please someone can help me in my case?

THX
Peter
