If the Ethernet cable is not connected at the time the LwIP_DHCP_task is running,
no IP address can received after reconnect the cable.
Does anyone has any idea how to solve it?

I don't know of any FreeRTOS examples that use DHCP. I suggest trying the lwIP
mailing list. It is very active and somebody will be able to help. Please report
back here when you have an answer.
