Ubuntu Live CD 7.10 can't find the wireless antennas in my new MacBook with 802.11b/g/n (Intel Core 2 Duo processor).

Hi !

enter these commands one by one in a terminal, as seen here http://doc.ubuntu-fr.org/macbookgutsy#sur_un_macbook_santa_rosa

sudo apt-get install ndiswrapper-utils-1.9
wget http://theflew.free.fr/truks/macwifi.zip
unzip macwifi.zip
cd macwifi/drivers/
sudo ndiswrapper -i bcmwl5.inf
ndiswrapper -l
sudo depmod -a
sudo modprobe ndiswrapper
sudo cp /etc/network/interfaces /etc/network/interfaces.orig
echo -e 'auto lo\niface lo inet loopback\n' | sudo tee /etc/network/interfaces
sudo ndiswrapper -m
echo 'ndiswrapper' | sudo tee -a /etc/modules
echo 'ENABLED=0' | sudo tee -a /etc/default/wpasupplicant

yeah... that's a lot, but copy&paste :-)

Tell me if it helps

Hi, Oliver,

Thank you so much for your kind help.

I wasn't able to get it to work, perhaps because I'm a novice at this point.

Here is what happened when I pasted each line into the Terminal. All
seemed to go well at first, till it reached the line that begins with
"bash."

I pray that you can look at this and tell me what to do differently.

Thank you so much for your time and help.

Sincerely, Macbook

OK. Let's explain a bit

first you installed the program ndiswrapper which allow to use windows wifi drivers on linux:
     sudo apt-get install ndiswrapper-utils-1.9

then you downloaded the appropriate windows driver...
     wget http://theflew.free.fr/truks/macwifi.zip

you unpacked the archive
    unzip macwifi.zip

you entered the unpacked archive...
    cd macwifi/drivers/

...but that failed, because the directory created is "drivers". So, enter those commands :
   cd drivers

now you are in the right directory. Let's installed the driver :
     sudo ndiswrapper -i bcmwl5.inf

verify that the driver is installed
     ndiswrapper -l

updating kernel modules
     sudo depmod -a

loading the module
     sudo modprobe ndiswrapper

doing some stuff to make it automatic at next boot
      sudo ndiswrapper -m
      echo 'ndiswrapper' | sudo tee -a /etc/modules

That should do. to copy and paste in linux, you can select something, and then paste using middle-click (ie the scroll wheel or both right left click) : you'll see, it is really useful ! hit enter only after entering a whole line of instruction. For instance, entering "sudo" only does not make any sense : sudo means SuperUser DO, this is to acquire administrative priviledge to enter an other command. usually, you will be warned if you do something meaningless like :

ubuntu@ubuntu:~$ sudo
 usage: sudo -K | -L | -V | -h | -k | -l | -v
 usage: sudo [-HPSb] [-p prompt] [-u username|#uid]
             { -e file [...] | -i | -s | <command> }

by the way, I see that you are doing it from the liveCD, aren't you ?? these changes won't be applied outside this very live seesion : if you install ubuntu on your system, you will have to go throught it again. So, I advise you to proceed to the installation, and then follow the above instructions
