ubuntu can't detect wifi mac

Question

I have installed ubuntu(12.04.1 LTS) on my mac air 6.1, but it can't detect any wifi. I was told that I should install a network card driver.

but I have tried to search on google but i got nothing. because I type: lspci -vvnn | grep 14e4 to detect the device and I got this: Network controller[0280]:broadcom corporation device 14e4:43a0 I saw lots of things about broadcom bcm** but I think mine is different from the bcm**.

can u help me? what should i do? thx in advance.

A later bcmwl-kernel-source package (i.e. bcmwl-kernel-source_6.30.223.30+bdcom-0ubuntu3) does have support for the chipset Broadcom BCM4360, PCI-ID 14e4:43a0. The catch is that this package was part of the Saucy release (i.e. Ubuntu 13.10) so for now it needs to be installed manually in Precise (i.e. Ubuntu 12.04). To determine which version you need, find out if you have a 32- or 64-bit installation:

arch

If your is 32-bit (i686), you need to dowbload this to your desktop: http://launchpadlibrarian.net/143917601/bcmwl-kernel-source_6.30.223.30%2Bbdcom-0ubuntu3_i386.deb

If 64-bit (x86_64), then this: http://launchpadlibrarian.net/143917424/bcmwl-kernel-source_6.30.223.30%2Bbdcom-0ubuntu3_amd64.deb

Both packages require dependencies. With a temporary wired ethernet connection, please do:

sudo apt-get install dkms libc6-dev linux-libc-dev
cd ~/Desktop
sudo dpkg -i bcmwl*.deb

Detach the ethernet, reboot and give us your report.
