Wireless problem

i have a compaq laptop with wireless built in and t was able to find and connect to my wireless at home and the other day i was able to see my wireless network but unable to connect or seem to get any response from it whatsoever ie: did not even show "limited or no connectivity". i share wireless with 1 other person in my house and they are able to connect so i have ruled out the modem/router as a problem. i have tried unplugging the modem to reset it with no luck. i am able to use my wireless and connect fine on campus so it is obviously not my wireless card and i can also connect to my router through a cable. please help me, thank you

 

yeah i realized where i posted after i wrote it, sometimes its so hard for me to find things on here, but they're very helpful, thank you very much =)
