How can I browse Mobile internet via PC

I am using Samsung champ-GT C3303i with Internet connection. Problem is, I want to use my mobile net in my Lappy-Compaq Presario cq-45 with Windows-7 OS. Alternatively I have installed NPS and Samsung Kies in my lappy, and tried many options but am not successful in connecting.
Every time I connect mobile via cable, it is showing Connecting to PC for a long time, but not connecting. Also Bluetooth is unable to connect to mobile while file sharing is possible through Bluetooth but not recognizing my mobile.
How can I connect my Mobile to PC to browse net in my Lappy, with Mobile as a Modem?
