Dell E1405 Network Settings: Kubuntu?

Alright, I own a one-year old Dell Inspiron E1405 model. The network controlles is listed as "Broadcom Corporation BCM94311MCG wlan mini-PCI (rev 01)". Can somebody please help me? I'm completely new and have very little knowledge of operating systems and/or linux. Thanks!

Hopefully you have a wired connection for this laptop.
Here is a link to get that card working.

p.s. I deleted your other post, please don't double post in the future
