[ Résolu ]Problème Atheros AR5007EG

Bonjour,
Je viens d'installer Ubuntu 12.04 64b, mais j'ai un problème avec le wifi; en effet, quand je souhaite me connecter en wifi, aucun réseau n'est détecté (alors que je me trouve juste à coté de ma box!). Dans la mesure ou dans la doc, il est dit que cette carte est supportée sans configuration particulière, je viens vous demander de l'aide!

Voila les résultats des commandes demandées :

Re : [ Résolu ]Problème Atheros AR5007EG

si c'est les 2 premieres commandes qui ont reglées le probleme,il faut les rendre persistantes

gksudo gedit /etc/modprobe.d/ath5k.conf

une page blanche s'ouvres
ajoutes
options ath5k nohwcrypt=1
enregistre et quittes gedit
redemarres le pc

Re : [ Résolu ]Problème Atheros AR5007EG

Et bien, je viens de rallumer mon PC, et le WIFI marche toujours très bien!
Donc est ce que tu me conseille quand même de faire ça:

gksudo gedit /etc/modprobe.d/ath5k.conf

une page blanche s'ouvres
ajoutes
options ath5k nohwcrypt=1

Ou ce ne sera pas la peine ?
Encore merci
