Ubuntu 18.04 - Impossible de switcher de Wifi

docaurelie

Bonjour,
J'ai deux soucis (probablement liés) avec ma connexion Wifi depuis que je suis en 18.04.
1. Je suis incapable de switcher de Wifi. Si je suis connectée à un Wifi et que je veux basculer sur un second, la connexion est refusée.
2. Si pour une raison ou une autre, je suis déconnectée d'un wifi, je suis incapable de m'y reconnecter, je dois rebooter l'ordinateur.
Même un "sudo service network-manager restart", ne résout pas le second problème.
Des idées?
Merci!

Bonjour,

Le 29/01/2019, docaurelie a écritBonjour,

Sur Ubuntu 18.04 avec une carte wifi rtl8723de, que j'ai réussi à faire fonctionner grâce aux informations trouvées ici : https://github.com/smlinux/rtl8723de
je n'arrive pas à me connecter à un Wifi issu d'un partage de connexion d'un téléphone (j'ai essayé avec un IPhone et un FairPhone (Androïd)).

Une idée?

Merci

Pense à faire le wificheck (et aussi de tenter d'installer le pilote de larry finger plutôt que celui que tu as trouvé)

> Ubuntu 18.04 - rtl8723de - Wifi partage de connexion
_ _ _

Il faut fournir, en te servant du Retour utilisable de commande, un [doc]wificheck[/doc] rassemblant les informations > Configuration wifi.

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

cqfd93 a écritAstuce pour copier / coller sans erreur :

triple clic gauche pour sélectionner et copier une ligne entière

clic molette pour coller dans le terminal

_ _ _

Essaye, pour installer le pilote wifi :

git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new/
git checkout origin/extended -b extended
make
sudo make install

Regarde au § 2 et début du § 3 > [Tuto] Pas de Wi-fi ? Eléments importants à vérifier pour désactiver le secure-boot.

Pour le réglage d'antenne > [Résolu] RTL8723DE : aucun réseau détecté

> [Résolu] Wifi non détectée d723

Ce n'est pas un doublon, j'ai fait deux sujets car ce sont deux ordinateurs différents, avec deux cartes wifi différentes et deux soucis différents...

Voici les informations pour l'ordinateur qui n'arrive pas switcher de Wifi et quand il se déconnecte, n'arrive plus à se reconnecter

Pour le second, que retourne :

sudo modprobe rtl8723de

docaurelie

Pour le second :
- si j'installe le pilote de larry finger plutôt que celui que j'avais trouvé (https://github.com/smlinux/rtl8723de) le partage de connexion fonctionne 🙂 mais il capte très mal le wifi, ce qui fait que si je suis dans une autre pièce que la boxe, il ne capte plus rien. C'est pour ça que j'avais installé un autre pilote.

Quand je tape la commande

sudo modprobe rtl8723de

Il ne me dit absolument rien. Il est actuellement avec le pilote de larry finger.

xubu1957

Tu as essayé le réglage d'antenne > [Résolu] RTL8723DE : aucun réseau détecté ?

_ _ _

Quel chiffrement sur la Box ?

Il faut un seul chiffrement WPA2, comme indiqué au § 1 > [Tuto] Pas de Wi-fi ? Eléments importants à vérifier.

docaurelie

J'avais essayé pas mal de chose, mais je n'avais pas vu cette page. La seconde commande à résolu le soucis! C'est donc bon pour le second ordi (me reste un soucis de scanner, mais c'est une autre histoire!).

Merci!

docaurelie

Pour le premier ordinateur, j'ai essayé d'installer les pilotes de larry finger et ça ne résout pas le soucis 🙁 Il est incapable de switcher de wifi et de se reconnecter au wifi quand il le perd.

Tente :

sudo modprobe -r rtl8821ce
sudo modprobe -a rtl8821ce

docaurelie

$ sudo modprobe -r rtl8821ce
modprobe: FATAL: Module rtl8821ce not found.

$ sudo modprobe -a rtl8821ce
modprobe: WARNING: Module rtl8821ce not found in directory /lib/modules/4.15.0-43-generic

Tente les mises à jour :

sudo apt update

sudo apt full-upgrade

Ca ne change rien...

Bonjour,

Un retour avec :

docaurelie a écritPour le premier ordinateur, (...) Il est incapable de switcher de wifi et de se reconnecter au wifi quand il le perd.

Fais un clic (droit ou gauche, ça dépend des variantes) sur l'icône de réseau,
> "Modifications des connexions"
> Sans fil
> Sélectionne l'un des réseaux qui t'intéressent
> "Modifier"
> Assure-toi que "Connecter automatiquement" soit bien coché.
> Enregistre.

Recommence pour le second réseau qui t'intéresse.

C'est déjà le cas. Puis il y a le soucis que quand il perd un réseau (peu importe la raison), il n'est pas capable de se reconnecter à ce même réseau.
