ISP : Ono

Hi to all!

I am using a TL-WDR3600 in conjunction with a thomson tcw710 from my internet cable provider (ONO - Spain) connected by supplied utp cable by TP-Link product.
Physically, I connected WAN port from TP-link to the only ethernet connector in the ISP device.
I configure the thomson ISP device in "Cable Modem" mode after disabling Firewalls, Wifi, filters and dhcp server for lan. Then i connect it to the tp-link router and configure it.

The problem i experienced is that TP-link router is acquiring and releasing ip from internet repeatedly and forever. By this way is impossible to have a Internet connection.
Then i copy here this behaviour of the router as you can see in the log.

But if i connect several PC at each time and i do a "ipconfig /release and /renew" i get a ip from isp with no problems and internet is accessible.

I also try switching on and off "ipv6", "dhcp server" on tp-link device, "unicast dhcp" in wan settings, clonning mac from pc's, crossover and simple utp cable and the result is the same: acquire and release de ip in two seconds period time. :p

Anybody knows what can be happen? Its really weird. :confused:

Thanks in advance.
