How to Install Broadcom Wireless card (BCM43XX)

I'm newbie in Linux and Ubuntu, but would like to improve my skills :)

I just installed Ubuntu 11.04 on my laptop (LENOVO B560, dualboot Windows 7 64-bit) and have got an issue with wireless connection - it doesn't work under Ubuntu.

My wireless adapter is Broadcom Corporation BCM4313 802.11b/g/n. I had installed Broadcom STA wireless driver, but it doesn't fix my problem - wireless network is disabled - I can't enable it.
I've got a message:

driver is activated but not currently in use.

It would be great if someone could help me to solve it.

Below is the output of the command sudo lshw -C network:
