Modifier, le chiffrement de la Box , comme le conseille toutafai dans de nombreuses discussions :

Le 14/11/2016, moko138 a écritEntretemps, j'ai retrouvé ce message ./viewtopic.php?pid=21563767#p21563767 de toutafai (8/2016) :
Ta box utilise un double chiffrement (à la fois du wpa1 et du wpa2), c'est certainement la source de ton problème.
Connecte toi sur l'interface d'administration de ta box et change moi cela pour
soit que du wpa1 TKIP,
soit que du wpa2 AES
(ne pas oublier d'enregistrer les changements sur ta box),
Une fois que ce sera fait, tu ne devrais plus avoir de déconnexions

(edit)

f.x0 a écritBonjour weimann23,

Essaies ceci :

sudo rfkill unblock all

Puis essaies d'actionner l’interrupteur du wifi (ou par touche) puis reboot

depuis : [RESOLU] impossible d'activer le reseau sans fil

Vianneyh

Merci pour ta réponse mais au final en cherchant j'ai trouver ce que c'était c'est l'antenne qui est sous l'écran en démontant le pc j'ai vu y avais des fils de casser j'ai du les ressouder et maintenant tout est ok .

xubu1957

Montres quand même :
