Proprietary Broadcom STA wireless driver doesn't work in Oneiric

[Ary Kleinerman]

In Ubuntu Oneiric 11.10, when you activate the Broadcom proprietary driver (Broadcom STA wireless driver) it is loaded but it isn't used. The solution that I found is to append the following two modules in /etc/modprobe.d/blacklist-bcm43.conf: "bcma" and "brcmsmac". One of them is documented in www.broadcom.com/docs/linux_sta/bcma.txt

My computer is a Lenovo G460 with a Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller.
You can see the problem because the Wireless led doesn't work until you blacklisted this two modules.

This problem wasn't in the previous Ubuntu version Natty
