Want to use wireless internet on my lenovo 3000 c200 and dont know what to do. Think my son deleted the wireless card or modem. we have a wireless ADSL2 Dink router and my son can get wireless internet on his x-box and his lap top want to know how i can set up my laptop too.

Did you try turning on the little Wi-fi switch ON the switch is just below and to the left of the touch pad (on the edge just below the latching area). Some people ignore the most obvious solutions, no offense.
look for your D-link in the resulting notification icon that your (now turned on) found new wireless locations.
