That is an ethernet card, used for broadband. If you do not have DSL, cable, or satellite internet service this card is of no use to you. If you have dial-up internet service, which you say is what you have, then you need a dial-up modem. A dial-up modem uses a regular phone cord, the same one you would use for a telephone. The plug on an ethernet card is a bit larger as it needs a different type of line and plug. To see if you have the card is installed correctly with the right driver, go to your Device Manager.
