If the problem is in dhcp, you should check the code in external/dhcpcd. Wifi uses dhcpcd in gonk to obtain the ip address. It's possible that there is an interoperability problem between dhcp client and server.

Hi Vincent...
Thanks for your reply.
Actually if you see the dmesg kernel log, seems to be, it fails to start the dhcpcd service init.
I am struggling to make it up. Do you guys having any idea on how to overcome this issue ?

dmesg log snippet:
