I'm running Ubuntu 12.10 on a MacBook Pro 9,2 (Mid-2012). I was able to successfully install and configure wifi using these instructions. Great! However, when I reboot, the wireless card is recognized, but no wireless networks are detected.

That is, however, until I close the lid and the computer is suspended. When I reopen the lid, networks are detected normally.

Here is the output from dmesg | greb b43:

[   20.542046] b43-phy0: Broadcom 4331 WLAN found (core revision 29)

Here is the output from lspci | grep BCM:

01:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM57765 Gigabit Ethernet PCIe (rev 10)
01:00.1 SD Host controller: Broadcom Corporation NetXtreme BCM57765 Memory Card Reader (rev 10)
02:00.0 Network controller: Broadcom Corporation BCM4331 802.11a/b/g/n (rev 02)

And b43 is included in my /etc/modules.

Any suggestions? Thank you.

Unfortunately, with Ubuntu 13.04 64bit, there is no out-of-the-box support for the wireless card of my macbook pro 9,2. But it can be activated by installing the package bcmwl-kernel-source:

sudo apt-get install bcmwl-kernel-source

That worked for me. On the other hand, the sd card reader (integrated ethernet and card reader on broadcomm bcm57765 chipset) does not work and I haven't found a solution yet. If anybody did so, please let us know.
