i am having a bsnl wll phone model no ct800p with a usb port for connecting the same with my computer operating with windows 7 and while i am trying to connect it for internet it shows the driver not installed and the device manager doesnt shows the modem. How can i add my modem with the OS WIN7. If possible how can i download the modem driver files free of cost from internet.
