Ubuntu 18.04 - Impossible de switcher de Wifi

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,

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

Modération: on va continuer sur le doublon ici

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 wificheck 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.

Astuce 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.

Re : Ubuntu 18.04 - Impossible de switcher de Wifi

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

Re : Ubuntu 18.04 - Impossible de switcher de Wifi

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 smile 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.

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.

Re : Ubuntu 18.04 - Impossible de switcher de Wifi

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!

Pour le premier ordinateur, j'ai essayé d'installer les pilotes de larry finger et ça ne résout pas le soucis sad 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,

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.
