Wireless Networks (firmware missing)

[jfkim]

Hello,

I recently installed 12.04 on my macbook pro, and am unable to connect to my wifi network. It claims that the "device is not ready, firmware missing."
I'm connected through ethernet at the moment and when I try to use "Additional Drivers" from System Settings, it says "No proprietary drivers are in use on this system."
So I'm stumped as to what the problem is and what firmware I am missing.

Any help would be greatly appreciated.
If it helps, after inputting "lspci" to terminal, I found this:
03:00.0 Network controller: Broadcom Corporation BCM4331 802.11a/b/g/n (rev 02)

We need just a bit more data. Please run and post:

lspci -nn | grep 0280

Thanks.

Ok here is what I get after running lspci -nn | grep 0280

03:00.0 Network Controller [0280]: Broadcom Corporation BCM4331 802.11a/b/g/n [14e4:4331] (rev 02)

Thanks

Your device is supposed to work with the driver bcma that's already installed in 12.04. We wonder why it isn't working already. Please run and post:

sudo modprobe bcma
dmesg | grep -e bcma -e wlan -e eth

Thanks.

Please hook up the ethernet and try:

sudo apt-get install linux-firmware-nonfree
sudo modprobe b43
dmesg | grep -e b43 -e bcma

Thanks.

Wow thank you so much, I am able to connect to wifi now.

After inputting "dmesg | grep -e b43 -e bcma", It gives me this:

Do I need to follow these last instructions and download the firmware? The wifi is working perfectly now...

If it's working perfectly, you probably don't need to do anything. If, on the other hand, you are an OCD nervous nellie like me that won't be able to sleep, I'd do so. Post back if you need assistance.

The 14e4:4331 is a new one to me. You will have helped quite a few searchers if you use thread tools at the top and mark Solved.

Okay I followed the link, and it instructed me to input this command
sudo apt-get install firmware-b43-installer

And it came up with this:

However, this link: http://wireless.kernel.org/en/users/...buntu.2FDebian
claims that it is supported..

That's what we get for doing things the right way; wrong results! Oh, well.

Let's use the stone axe. Please download the attached file to your desktop and right-click it and select Extract Here. Now open a terminal and do:

sudo cp Desktop/mimo/* /lib/firmware/b43

Now we unload and reload the drivers so it sees the new firmware:

sudo modprobe -r b43
sudo modprobe -r bcma
sudo modprobe b43
sudo modprobe bcma

Are there any new messages?

dmesg | grep -e b43 -e bcma

Look later than your previous timestamp of [ 20.624308] b43-phy0 ERROR:
