Just bought this laptop - cannot get the Wireless

If wireless card is listed in device manager under network adapters-that means you dont have to install it. If you running on vista, go to control panel and find ssomething like wireless contol manager or wireless assistant and see if its not disabled there. may also be disabled in bios settings. on windows xp-check if windows has possibility to manage wireless networks or its blocked by third party software. for example i use bt voyager wireless card and its managed by bt software. built in cards are likely managed by windows. type services.msc in run box and see if wireless zero configuration service is enabled.
