no internet connection?

[adwait]

I am having some trouble connecting to internet. I recently moved and relocated my internet services. but since then I am having unable to connect to internet. I have received the configuration details from my ISP however I am still not able to connect. I am using a laptop with Win 7 and none of my other devices (tablet, phone etc...) are able to connect.
I am using a belkin F5D7633-4a ( wireless ADSL 2+ G router modem).

Modem issue:
I am using 192.168.2.1 to get to the router utility page. When I enter my config details and click apply changes, the page just refreshes with error " Internet not connected". Laptop is recognizing the internet connection.

Laptop issue:
if I try and configure through my laptop - I go to control panel>network share connection>setup new network> put my details in> it gives me error 651.

HELP!!!
