Help Installing Wireless card on Dell Inspiron E1505 with Ubuntu

[Papenco]

Ok, the problem is that I can´t install the driver for my Wireless card, so I can´t connect to wireless networks. I´ve already read some tutorials on this but it still doesn´t work. I´ve made a partition for ubuntu and I still have a partition with windows XP. Is there any solution for this problem?:confused:
Thanks for your help.:)
