**** habilitar wifi en ubuntu 11.04 ***

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-fwcutter

Since Ubuntu 11.04 Natty Narwhal additional installation of the package firmware-b43-installer can be helpful and/or necessary, respectively:

~$ sudo apt-get install b43-fwcutter firmware-b43-installer

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.

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
