Problem with connecting belkin router to adsl modem/router

"Try to disable DHCP server in the EXTRA router IE the thomson router. then it will be as a pass through or SWITCH and you should not have any more problem. Remember that after you turn off DHCP you will not be able to reach that routers home page untill you do a hard reset on the router. also remeber to plug the connection into one of the ports 1-4 and not the WAN or Internet port. once done you shouldn't have any more problems(the most probably problem is that both routers are giving ip address but on Two different gateways IE 192.168.0.1 and 192.168.1.1 if this is true the you will NOT get internet because the two gateways are not communicating.) so by getting rid of one DHCP the other gets to create the connections.

Good LUCK!!!"
