ubuntu 12.04 / BCM4312: device is present but can't do much


Ok, guys, this is a Dell XPS M1530 where I'm trying to set up the wireless to work. The device is present but can't do much.

Code:
$ sudo iwlist scan
lo        Interface doesn't support scanning.

eth2      Failed to read scan data : Invalid argument

eth0      Interface doesn't support scanning.

Do you have the firmware for that Broadcom device installed?

Things about firmware have to deal with fwcutter, right? I think the package will take care of that but you have instructions to follow? perhaps doing some tricks can get this done.

You can either use the Additional Driver program or you install the package firmware-b43-lpphy-installer via apt-get. This package will automatically download, strip and install the firmware. Keep in mind that you need a working Internet connection for that package to work, so you have to temporarily use a wired connection.

I tried getting the interface up with ip link, the led where I see if the wireless is up lit up for a fraction of a second then turned off and the interface is still down.

This is from dmesg

Code:

[16622.657929] ADDRCONF(NETDEV_UP): wlan0: link is not ready
And this is from iwlist afterwards:

Code:
$ sudo iwlist scan
lo        Interface doesn't support scanning.

wlan0     Interface doesn't support scanning : Network is down

eth0      Interface doesn't support scanning.

Do you have a hardware switch for WLAN on that device?
What is the output of
Code:
rfkill list

About question 1: I don't think there's any switch involved here.... but can you throw a command to make sure of it?

About question 2:
