Ma carte wifi se déconnecte toute seule...
Bonjour,
J'ai acheté un eMachine e443 à base d'AMD C-50 et de chipset AR9285, le problème (en dehors de l'affichage qui n'est pas satisfaisant mais c'est le sujet d'un autre topic) est que non seulement ma carte wifi se déconnecte toute seule au bout d'une dizaine de minutes et qu'il lui est impossible de se reconnecter ensuite, mais qu'en plus elle fait également sauter la connexion Wifi de mon netbook situé à proximité. Je vous donne les informations demandées :
Remarque : j'utilise actuellement Linux Mint 12, mais je l'ai installé pour voir si j'avais le même problème qu'avec Ubuntu 11.10, et oui j'ai le même problème...
Par avance, merci !

Re : Ma carte wifi se déconnecte toute seule...
Merci de ta proposition !
Cela a fonctionné bien 5 minutes, mais j'ai rapidement dû repasser en filaire la carte n'arrêtait pas de se déconnecter, pour ne plus y arriver du tout.
J'ai réinstallé Ubuntu 11.10 et ai fait les mises à jour. En désespoir de cause, je vais tenter de passer par ndiswrapper.
[EDIT]Bon ben ndiswrapper ne marche pas...[/EDIT]
