Network manager applet and wifi

And when I right-click network manager, information connection, I get the error "no valid connection available".

Please, tell us the output of these commands:

lshw -c network

01:00.0 Ethernet controller [0200]: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter [168c:001c] (rev 01)

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Yesterday I tried Madwifi. I made what is been told in https://help.ubuntu.com/community/WifiDocs/Device/AR5007 but I arranged nothing (Windows tells me that my Atheros Card is a an AR5007 one; I have a dual booting system). Everything went fine, with no errors.
Did I miss anything when I tried Madwifi? I installed Madwifi following the instructions, I switched Ndiswrapper off, I rebooted, and my network didn´t work at all (System, Administration, Hardware Controllers doesn´t seem to work well; when I try to activate the grey button next to Mmadwifi and make it turn green nothing happens). Then I reswitched Ndiswrapper on, I rebooted, and my networked worked again, but Network Manager didn´t.
I insist: my wifi works but my Network Manager doesn´t.
Why does Windows says that my Card is an AR5007 one and Linux that it's an AR242X one? Is it the same?
Do you need again my lshw -c network and my lspci -nn | grep working under Madwifi?

Do I have now two controllers (madwifi and ndiswrapper) fighting one another? Do I have to blacklist something?

> Why does Windows says that my Card is an AR5007 one and Linux that it's an AR242X one? Is it the same?

AFAIK, the AR5007 is the name of the card, and AR242X is the name of the chipset.

Please, try uninstalling BOTH madwifi and ndiswrapper. Add the jaunty-backports repository and install the package linux-backports-modules. Then reboot. Ensure the ath5x module is being loaded (should be listed in lsmod).

Sorry by the brief instructions, I'm not in my computer right now so I can't check the steps.

I do need more details. I'll wait for them. I'm not an expert.
How do I add jaunty backports repository?
How do I install linux backports modules?

To add the jaunty backports repository:

 - Main menu: System -> Administration -> Software Origins
 - Tab: Updates
 - Check "Unsupported updates (jaunty backports)"
 - Close and choose yes when answered to reload the packages information.

To install linux-backports-modules:

 - Main menu: System -> Administration -> Synaptic Packets Manager
 - Rapid search: Type "linux-backports"
 - Packages list: Select "linux-backports-modules-jaunty". Right click. Select "Mark for Installation". If asked for mark additional changes, choose "Mark".
 - Click Apply and wait. A Summary will be shown. Click Apply.

After a reboot, to ensure the module is being loaded:

 - Main menu: Applications -> Accesories -> Terminal
 - Type this command: lsmod

You should see the ath5x module listed. If not listed, or if something goes wrong, please do the following:

- Main menu: Applications -> Accesories -> Terminal
- Type this command: lsmod
- Type this command: lshw -c network

Wait for the command completion and then copy & paste all the contents of the terminal here.

How should I uninstall Madwifi? With sudo ./madwifi-unload and then sudo ./find-madwifi-modules.sh $(uname -r)?
With respect to ndiswrapper, must I uninstall ngdisgtk, ndiswrapper-utils-1.9 and ndiswrapper-common, which are all three in my Synaptic?
¿Se puede hablar en español?

Si configurases la pregunta como en español, te hablaba en español desde el principio, pero hacer un popurrí ahora no me apetece. Para la próxima elige español a la hora de preguntar :P

On synaptic, uninstall ndiswrapper-utils-1.9 and I think that should be enough. As I read on [1] madwifi wiki, yes, that commands should be enought too.

I haven't got a wifi anymore. Working with eth0.

Please, check that you have installed linux-backports-modules-jaunty.

Yes, I have them installed.

Is this Bug #309195 ?

Nope. Check you have also installed the package linux-backports-modules-2.6.28-11-generic. The ath5k module is there, so if you have this package installed, you should have the ath5k module.

I have this package installed.
But ath5k is not in lsmod and modprobe ath5k says "FATAL: Module ath5x not found".

Estoy cansado del tema. Voy a volver a poner el Ndiswrapper, que me funciona, aunque mal (la wifi funciona, el network manager no, y el roaming mode tampoco).
De todas formas, he aprendido mucho. Ya sé lo que el el chipset, y sé que hay 3 maneras de que funcione una tarjeta wifi: el Ndiswrapper, el Madwifi y los linux-backport-modules (antiguamente no sabía ni lo que eran).
Seguiré buscando por mi cuenta, y cuando ponga el Karmic, haré otra intentona.
Muchas gracias por todo.
Pincho en "Problem solved", aunque no sea verdad.

I feel very sorry about this. You should have the module ath5k... maybe since it seems that you haven't uninstalled ndiswrapper properly, the system hides it for whatever reason. Anyway, since networkmanager doesn't seem to work ok for you, try wicd instead. http://wicd.sourceforge.net/

Lo siento, de verdad. Deberías tener el módulo ath5k... puede que como parece que no has desinstalado bien ndiswrapper, el sistema lo esconda por algún motivo. De todas formas, ya que networkmanager parece que no te funciona, estaría bien que probases wicd en su lugar. http://wicd.sourceforge.net/

Ya lo he puesto. Muchas gracias.

Quería añadir que mi tarjeta wifi Atheros funciona ya perfectamente con el Karmic. Sin embargo, he tenido que ponerlo "afresh", como dicen los americanos, porque con la actualización de Jaunty a Karmic dejó de funcionar del todo, incluso con el Ndiswrapper.
Muchas gracias a todos, especialmente a Jorge Suárez de Lis.
