Pas d'internet sur un seul réseau

arauschdet

Salut !

Je viens d'achever mon installation de Ubuntu (16.04.3), et je remarque un problème étrange.
J'ai d'abord essayé de me connecter à mon routeur, mais internet n'y était pas disponible à ce moment-là. Je passe alors sur mon en hotspot téléphone pour faire les premières installations.
Mais lorsque internet est revenu sur mon routeur, la connexion entre ce dernier et mon Ubuntu a beau se faire (logo wifi en haut à droite), je n'ai aucun accès à internet.

Comment régler ça ?
Merci d'avance,

Bonjour,

Si c'est la version 17.10, voir > Anomalies réseaux en Ethernet sur la version 17.10

arauschdet

Ce n'est pas la 17.10, j'ai pris le dernier build disponible ici https://ubuntu-fr.org/telechargement (16.04.3), je ne savais pas qu'il y en avait des nouveaux.

xubu1957

Tu dois avoir un noyau 4.13.

Fournis le noyau actif :

uname -a

arauschdet

Bon je suis face à une situation étrange.
Hier dans la soirée je me connecte pour vérifier le noyau, internet fonctionne (avec le même réseau). Ce matin, ça ne fonctionnait plus, maintenant ça refonctionne.
Dans le doute, uname -a fournit :

Il serait possible de régler le problème de connexion avant la mise à jour du noyau ? Le débit que j'ai via mon téléphone est très lent

xubu1957

Bonjour,

Pour un noyau 4.10 (copié d'une version 17.04), voir > Anomalies réseaux en Ethernet et Wifi sur la version 17.04

arauschdet

Bonjour,
Le problème que j'ai n'est pas sur ce sujet. Mon pc se connecte bien au wifi : j'ai bien l'information 'Vous êtes désormais connecté au wifi' et le nom de mon réseau, mais impossibke d'accéder a internet (sauf, comme dit, parfois, dans des conditions spéciales peut etre ?) ni même a l'administration de mon routeur.

xubu1957

Bonjour,

Il faudrait d'abord passer les mises à jour :

sudo apt update

sudo apt full-upgrade

et donner, en se servant du : Retour utilisable de commande, ces informations : Configuration wifi ou un [doc]wificheck[/doc]

Nota : un fichier wificheck.log est créé dans votre répertoire personnel, collez l'intégralité de son contenu dans votre discussion.

arauschdet a écrit Je viens d'achever mon installation de Ubuntu (dernier build),

En général,
1) c'est justement ça, le problème ;
2) La version la plus stable 16.04.1 donne toute satisfaction. Et l'installer est la plus rapide des solutions. Personnellement c'est, à ta place, ce que je ferais.

arauschdet

@moko138 : Ce n'est pas la version 17.10, mais la 16.04.3, désolé, j'ai cru que celle que j'avais téléchargée était la dernière.
@xubu1957 : J'avais déjà fait sudo apt update mais n'ayant pas accès à internet, je ne peux pas effectuer full-upgrade.
Voici toutes les commandes et leur retour demandées sur le post "Configuration wifi" :

Pour ton noyau :

uname -r -m
4.10.0-28-generic x86_64

copié sur la version 17.04, voir > Anomalies réseaux en Ethernet et Wifi sur la version 17.04

Je viens de lancer un apt update et un apt full-upgrade, j'ai maintenant :

uname -r -m
4.13.0-26-generic x86_64

Pourtant, avec la modification de NetworkManager.conf ou sans, la connexion wifi ne fonctionne toujours pas...

Tente :

sudo modprobe -r iwlwifi
sudo modprobe -v  iwlwifi

Fais déjà ce que te conseille xubu1957.

Mais

arauschdet a écrit@moko138 : Ce n'est pas la version 17.10, mais la 16.04.3, désolé, j'ai cru que celle que j'avais téléchargée était la dernière.

Justement, l'erreur c'est de chercher la dernière !
Que ce soit la 17.10 ou la 16.04.3 à noyau - changeant - de 17.10 !

Sache-le à l'avenir, la version sans problèmes, c'est la 16.04.1,
c'est toujours la version LTS avec extension .1
Et elle est maintenue cinq ans.

Le seul intérêt d'une version LTS avec extension .3, c'est d'avoir les tout derniers pilotes, et uniquement quand on a du matériel si récent qu'il n'est pas pris en charge par la 16.04.1.
Mais ça s'obtient au prix de plâtres comme ceux que tu es en train d'essuyer !

EDIT : orthographe.

@moko138 : Je me suis mal exprimé, ce que je cherchais à faire c'était prendre la dernière version stable et complètement fonctionnelle (je suis nouveau dans l'univers de l'installation linux, ça c'est sans doute vu). Etant donné que j'ai téléchargé la version qui était proposée en première au téléchargement sur ce site, je pensais que c'était celle-là que je cherchais ! Maintenant je saurai

Essaye :

sudo service network-manager restart

arauschdet

Le gestionnaire de réseau s'arrête et se redémarre, mais la connexion ne fonctionne toujours pas...
