FXT009 with Fxte02 Ethernet Expansion

Hello community,
I may have the same problem.
@mlucarelli, Could you explain which commands when you said :
“I found the commands to start the ethernet and to take the IP address in the DHCP.” ?

My FXT009 came with FXTE02 embedded. But i can’t manage to get any IP adress, the LED don’t get ON or blinked.
I’m noob with that modem, but when i tried the command to enable ETH, i get “ERROR” back.

AT+ETH=1
ERROR

It seems that the FXT02 isn’t enabled or activated, and i don’t find howto.

As you may ask:
