Broadcom Headache-No wireless

[Sequoia Bird]

I have ubuntu 12.10, and after I installed the updates about two weeks ago the wireless card stopped working. I have a Broadcom 4312 wireless card.

rfkill list

returns nothing.
Software Sources says I am using the proprietary driver. I have fwcutter installed.

lshw -C network

returns:

Thanks for any help!

Which of these do you have installed?

firmware-b43-installer
firmware-b43-lpphy-installer
bcmwl-kernel-source

[Sequoia Bird]

I have firmware-b43-lpphy-installer installed

Should I change that?

Thanks

[newb85]

No, I don't think so.

Something changed, but it still doesn't work. Thanks for the help though...

EDIT: after a reboot it's back at square one, same situation as in my first post.

[squakie]

Post back the output of lsmod so we can see which modules are getting loaded at boot.

Hi, copy and paste this command in the terminal (ctrl+alt+t) please:

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script

It will download a script and create a text file in your home folder with wireless information so we can see the condition of your wireless at this time and the Mac address, WPA key and WEP key are removed for your security, then reply back and attach the netinfo.txt file.
Thanks

Sorry for the delay--
