RTL8822BE Aucun adaptateur wifi trouvé Ubuntu 18.04.1

Blackeagle360

Bonjour, après beaucoup de recherche je n'arrive pas à trouver de solution a mon problème, pourriez-vous m'aider ?
Je suis débutant avec Ubuntu, je tien donc à m'excuser si je ne comprend tout.
Merci

Bonjour,

Pour la carte :

Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:b822]

Essaye :

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

et aussi :

sudo modprobe rtl8822be

> [Résolu] Deconnexion Realtek 8822BE

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

Blackeagle360

Merci xubu1957 pour ta réponse rapide, lors du :
git checkout origin/extended -b extended

j'ai ce message :

val@val-HP-Laptop-15-db0xxx:~/rtlwifi_new$ git checkout origin/extended -b extended
La branche 'extended' est paramétrée pour suivre la branche distante 'extended' depuis 'origin'.
Basculement sur la nouvelle branche 'extended'

est-ce normal ?

xubu1957

Essaye alors :

git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
sudo modprobe -r rtl8822be
sudo modprobe rtl8822be

si l'on suit > github.com/lwfinger/rtlwifi_new

Update for 18.04

The Realtek RTL8822BE is supposed to work out of the box in Ubuntu 18.04.

During installation, Ubuntu should detect what Wifi Card you have and install the correct driver for it, but to search for any further available drivers on Ubuntu 18.04, go to the Software & Updates program and click the Additional Drivers tab.
(If you're having trouble finding 'Software & Updates', clicking 'Activities' in the top left of your desktop and typing 's' in the search box should be enough to show the available relevant programs)

Another occasional 'quirk' that has occurred is for Secure Boot to have an issue with the signing of the driver and preventing it from being loaded.
You can make sure that Secure Boot is disabled by checking your machine's BIOS settings (usually accessed by pressing a specific key chosen by your manufacturer, such as f2 or esc when you switch your computer on, but the Grub Menu also lets you select 'System setup' to take a look at your options).

In a few cases, a Software or Hardware block can be preventing the Wifi from connecting. You can check for this by typing rfkill list into the terminal.

Le Realtek RTL8822BE est supposé fonctionner immédiatement sous Ubuntu 18.04.

Au cours de l’installation, Ubuntu doit détecter la carte Wifi que vous possédez et installer le pilote approprié, mais pour rechercher d’autres pilotes disponibles sur Ubuntu 18.04, accédez au programme Logiciels et mises à jour, puis cliquez sur l’onglet Pilotes supplémentaires.
(Si vous ne parvenez pas à trouver "Logiciels & mises à jour", cliquer sur "Activités" en haut à gauche de votre bureau et saisir "s" dans le champ de recherche devrait suffire à afficher les programmes pertinents disponibles.)

Un autre «problème» occasionnel est que Secure Boot ait un problème avec la signature du pilote et l’empêche de le charger.
Vous pouvez vous assurer que le démarrage sécurisé est désactivé en vérifiant les paramètres BIOS de votre ordinateur (généralement accessibles en appuyant sur une touche spécifique choisie par votre fabricant, telle que f2 ou echap lorsque vous allumez votre ordinateur, mais le menu Grub vous permet également de sélectionner Système. configuration "pour examiner vos options).

Dans quelques cas, un bloc logiciel ou matériel peut empêcher le Wi-Fi de se connecter. Vous pouvez vérifier cela en tapant rfkill list dans le terminal.
