i got my aunts old laptop for christmas, its a dell inspiron b130, and when i got it i turned it on and went online wirelessly. when i got home i tried to connect to my wireless internet but it just aint happining, i took it to a friends house and it wouldnt connect their either, even got a new modem, and still no. but i know the wireless card in it works because i DID use it the day i got it. any suggestons?

i dont think thats the problem cuz my friend brought his laptop over and it connected to our wireless, so you dont have to add it. and my aunt used to take it to starbucks all the time and she said it would auto connect to the wifi there
