I was read that subject : http://ubuntuforums.org/showthread.php?t=2011756

and i follow it step by step in the page n 1 , then i was connect but after i restart my macbook again , i was lost the wifi connection.i dont know why or whats the problem exactly.

every time I run this command:

dmesg | grep -e b43 -e bcma

I get this output:

[ 2012.769684] bcma-pci-bridge 0000:02:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17

[ 2013.371031] b43-phy0: Loading firmware version 666.2 (2011-02-23 01:15:07)

and to get the connection again every time i must entery that code in the step of reload driver.

How i can let the ubuntu see my wifi and wireless device automatically when i reboot my computer????

Is the code you enter:

sudo modprobe b43

If so, let's get the system to load the driver b43 automatically:

sudo su
echo b43 >> /etc/modules
exit
