Hardware Version : Not Clear

Firmware Version :

ISP :

Hi, i have a Archer D7 v1, firmware 1.6.0 (16022016) which i used to use with a ADSL+ provider with no issues.
After getting NBN to my house, i try to configure the D7 as Wireless router, and plugged the NBN in the port 4/wan.
What is happening is that the D7 cannot get an IP in the Port4/WAN interface.
It is not an issue with my NBN as i can use my old router fine.
Seen the logs, the D7 is getting a DHCK NAK when trying to get an IP.
I tried to clone my MAC despite i really dont belive this is the issue considering i can use a telstra router in my optus nbn.

I saw a similar case in another forum without answer too... http://forums.whirlpool.net.au/archive/2335056


Any ideas of what is going on?

thanks!
