is this the steps i need to do.
b43 - No Internet access
If you do not have any other means of Internet access on your computer, you will have to install b43-fwcutter and patch packages from the install media. After that you will need to setup firmware manually (without the firmware automatically downloading and being set up).
Setp 1.
b43-fwcutter is located on the Ubuntu install media under ../pool/main/b/b43-fwcutter/ and patch is located under ../pool/main/p/patch/ or both in the official repositories online.
Double click on the package to install or in a terminal (under the desktop menu Applications > Accessories > Terminal) navigate to the folder containing the package and issue the following command:
:/b43-fwcutter/$ sudo dpkg -i b43-fwcutter*Step 2.
On a computer with Internet access, download the required firmware files from
http://downloads.openwrt.org/sources...a-3.130.20.0.o and
http://mirror2.openwrt.org/sources/b...0.10.5.tar.bz2
Step 3.
Copy the downloaded files to your home folder and execute the following commands consecutively in a terminal to extract and install the firmware:
~$ tar xfvj broadcom-wl-4.150.10.5.tar.bz2
~$ sudo b43-fwcutter -w /lib/firmware wl_apsta-3.130.20.0.o
~$ sudo b43-fwcutter --unsupported -w /lib/firmware broadcom-wl-4.150.10.5/driver/wl_apsta_mimo.oStep 4.
Under the desktop menu System > Administration > Hardware/Additional Drivers, the b43 drivers can be activated for use.
Note: A computer restart may be required before using the wifi card.
LiveCD/LiveUSB
Note: The install media contents are mounted under /cdrom of the filesystem.
Step 5.
For temporary use with the LiveCD and LiveUSB environments, instead of a computer restart, in a terminal issue the following commands:
~$ sudo modprobe -r b43 ssb
~$ sudo modprobe b43
or this
b43 - Internet access
If you have some other kind of Internet access on your computer, you can download the firmware by simply installing the b43-fwcutter package which does the download and setup for you automatically.
Step 1.
To install b43-fwcutter issue the following command in a terminal (under the desktop menu Applications > Accessories > Terminal) and follow the prompts:
~$ sudo apt-get install b43-fwcutterStep 2.
Under the desktop menu System > Administration > Hardware/Additional Drivers, the b43 drivers can be activated for use.
Note: A computer restart may be required before using the wifi card.
