Problem connecting to Internet using Gigaset SE568 W/L Router

Hi

I have Gigaset SE568 router used in UAE and brought to India. I have been having hell a lot of problems in internet connectivity using Dataone Broadband of local IP provider, BSNL, India.

I have been able to configure the router and stay connected though, I am not able to open the browser and I get the message "cannot find server". I have tried all the permutations and combinations and the solution is still elusive.

Can you please assist me to solve the problem ?
