Sab Mar 28 14:43:33 UTC 2009

Juan Carlos buenos días, le pongo los pasos que yo seguí para dejar en
funcionamiento esta misma tarjeta en un lenovo sl 500, espero también
solucionen su problema, saludos.

  Removing old modules
¶<http://madwifi-project.org/wiki/UserDocs/FirstTimeHowTo#Removingoldmodules>

For this step you must be logged on as root.

First, set all your MadWifi
<http://madwifi-project.org/wiki/MadWifi>devices down:

ifconfig ath0 down
ifconfig wifi0 down
#Repeat these 2 ifconfig lines for every MadWifi device you have (ath1, etc)

Assuming that you're inside the
MadWifi<http://madwifi-project.org/wiki/MadWifi>directory, execute the
following scripts to remove the current modules from
your system and its memory:

cd scripts
./madwifi-unload
./find-madwifi-modules.sh $(uname -r)
cd ..

You should then be asked if you are sure that you want to remove the old
modules.
Building MadWifi <http://madwifi-project.org/wiki/MadWifi>
¶<http://madwifi-project.org/wiki/UserDocs/FirstTimeHowTo#BuildingMadWifi>

Now that you have the MadWifi
<http://madwifi-project.org/wiki/MadWifi>code, it's time to compile it
into the actual driver. Thankfully, this is
easy.

Assuming that you've met all of the requirements above, and you're inside
the MadWifi <http://madwifi-project.org/wiki/MadWifi> directory, you can
just type:

make

Which will start the build process. Watch for any questions you might be
prompted to answer - when it finishes, quickly scan through for any errors.
If everything went according to plan, you can proceed to the next step. Make
sure you have all the
Requirements<http://madwifi-project.org/wiki/Requirements>or the build
process may fail.
Installing MadWifi <http://madwifi-project.org/wiki/MadWifi>
¶<http://madwifi-project.org/wiki/UserDocs/FirstTimeHowTo#InstallingMadWifi>

This step will take the built MadWifi<http://madwifi-project.org/wiki/MadWifi>,
and install it on your system. Once again, make does all of the work for
you.

This step needs to be done as *root*, so either type su and enter
*root's*password, or if you have it set up (e.g. Ubuntu), prefix the
following
command with sudo.

To install the driver, type:

make install

This will copy all of the modules, tools and man pages to the correct
directories on your system. You've now completed the basic install.
Loading the MadWifi <http://madwifi-project.org/wiki/MadWifi> Module
¶<http://madwifi-project.org/wiki/UserDocs/FirstTimeHowTo#LoadingtheMadWifiModule>

This step will load the MadWifi
<http://madwifi-project.org/wiki/MadWifi>driver module into your
running system. This essentially lets all other
software know how to talk to your
MadWifi<http://madwifi-project.org/wiki/MadWifi>hardware.

This step needs to be done as *root*, so either type su and enter
*root's*password, or if you have it set up (e.g. Ubuntu), prefix the
following
command with sudo.

To load the driver module, type:

modprobe ath_pci

If after running this command ifconfig doesn't show the additional wireless
interface you might need to reboot. If you have any problems with building
the MadWifi <http://madwifi-project.org/wiki/MadWifi> driver, please refer
to UserDocs/BuildProblems<http://madwifi-project.org/wiki/UserDocs/BuildProblems>.

Creating an Interface
¶<http://madwifi-project.org/wiki/UserDocs/FirstTimeHowTo#CreatinganInterface>

MADWiFi supports *virtual access points*, which means you can create more
than one wireless device per wireless card. By default, a *sta* mode VAP is
created, which is MadWifi <http://madwifi-project.org/wiki/MadWifi> talk for
a 'managed mode wireless interface'.

*If your svn snapshot is more recent than the 23rd January 2006,
(r1407<http://madwifi-project.org/changeset/1407>
**) than you can skip the following step:*

If not, then follow these instructions to make a normal *station* mode
interface. Type (as root):

wlanconfig ath0 create wlandev wifi0 wlanmode sta

If wlanconfig <http://madwifi-project.org/wiki/UserDocs/wlanconfig> doesn't
work, you retry it after executing
'wlanconfig<http://madwifi-project.org/wiki/UserDocs/wlanconfig>ath0
destroy'.

Now, if you type iwconfig, you should see a list like the following:

eth0      no wireless extensions.

lo        no wireless extensions.

wifi0     no wireless extensions.

ath0      IEEE 802.11g  ESSID:""
          Mode:Managed  Frequency:2.457 GHz  Access Point: 00:00:00:00:00:00
          Bit Rate:0 kb/s   Tx-Power:20 dBm   Sensitivity=0/3
          Retry:off   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=0/94  Signal level=-95 dBm  Noise level=-95 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

Then we need to bring up the wireless interface. This is done by typing (as
root):

ifconfig ath0 up
