And in this page says how to install wifi directly with b43-fwcutter:

https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#Identifying Your Card/Driver

If you dont have Internet access go to other PC with Internet and download this files:

1.- ndistgtk_0.8.5-1_i386.deb, doble click like the video shows (with the driver in your directory)

If you dont have the diver then:

2.- get this two files: a) wl_apsta-3.130.20.0.o
b) broadcom-wl-4.80.53.0.tar.bz2

In this page are the links and the instructions:

http://techie-buzz.com/foss/wifi-ubuntu-install-broadcom-drivers.html

3.- This two files should be at /home/administrator user or you local directory.

4.- open a terminal and write this lines:

~$ 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.o

If there’s no problems then …

5.- The Step 4. from WifiDocsDriver says:

Under the desktop menu System > Administration > Hardware/Additional Drivers, the b43 drivers can be activated for use.

If you cant activate the wifi try to install the packages form Live CD, install the drivers from

../pool/main/b/b43-fwcutter/
and some other files that you need.

Get the CD with UBUNTU, open the carpets and search all packages you need.

I surf in win 7 and I foun the driver: Atheros Communications Inc. (R) AR81 Family Gigabit/Fast Ethernet Driver
Atheros Communications Inc.
10/12/2010
Ver. 10.0.36

But I cant copy the driver to /home directory. I’m new in Linux so i dont know how to up the eth0 or wireless.

In the terminal I type: lspci and I get this:

Atheros Communications Device 1083 (revc c0)
Broadcom Corporation Device 4357 (rev 01).

Ethernet controller [0200]: Atheros Communications Device [1969:1083] (rev c0)
Network controller [0280]: Broadcom Corporation Device device [14e4:4357] (rev 01)

Well, you said that the files ar****.inf and ar***.sys shoul be copy and /home directory, but … where I can get this files, in win7 they aren’t.

Could you please tell me wheere i can get this two files, and where I can get the the program –> ndiswrapper.
