Connecté au wifi mais pas d'internet

haboub

Salut tout le monde! J'ai fais hier le mise a jour d Ubuntu 17.04.
Le probleme est, que je suis obligé de passer par une connexion câble pour avoir internet sur Ubuntu, car quand je veut me connecter a mon reseau, il me marque qu'il est connecté mais je ne peut pas accéder a internet. j'ai besoin de votre aide .

Bonjour,

Regardes si tu peux appliquer cette solution :

Erwan28250 a écritBonjour sendscan 🙂,

J'ai eu moi aussi ce problème sur Ubuntu 17.04 avec une clé wifi TP-LINK WN722N et j'ai réussi à résoudre le problème grâce à cette solution (en anglais par contre).

J'espère avoir pu t'aider 😉.

Erwan

sendscan a écritBonsoir à tous,

je vois que plusieurs d'entre vous ont essayé de m'aider. Merci à tous, et plus particulièrement à Erwan28250, dont la solution a fonctionné. Merci à toi !

Voici la solution en français, au cas où quelqu'un en aurait besoin :

Dans un terminal, lancer la commande suivante :

sudo -H gedit /etc/NetworkManager/NetworkManager.conf

Dans le fichier qui s'ouvre, ajouter à la fin les lignes suivantes :

[device]
wifi.scan-rand-mac-address=no

Enregistrer le fichier et le fermer.

Dans le terminal, taper la commande suivante :

sudo service network-manager restart

Le Wi-fi doit maintenant fonctionner !

Pour ta carte wifi :

Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01)

suite au bug connu : bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1572659

Depuis la version 16.04, il suffit de désactiver le secure boot.

Voir notre documentation : [doc]desactiver_secure_boot[/doc]

et toujours vérifier, 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

merci beaucoup ça bien marcher maintenant j ai accès a internet grâce a ton astuce 🙂 🙂 😃
