RTL8821CE / Plus de wifi

billgastrik

Bonjour,
J'utilise ubuntu 18-04.
J'ai toujours eu une connexion wifi faible, mais depuis une récente mise à jour, je n'ai plus de connexion du tout.
Quelqu'un pourrait-il m'aider à trouver une solution, s'il vous plaît ?

On ne voit pas l'interface wifi !

Je vais essayer d'obtenir du renfort.

C'est avec une Freebox ?

Bonjour,

@xubu : au #3 on voit qu'il y a 2 modules WIFI qui sont gérés par dkms, rtlwifi-new et rtl8821ce. Lequel faut-il? Je pense qu'il y a besoin de remettre à jour les sources (et pour le rtl8821ce, où se trouvent les sources, dans quel git?)

Avant de refaire quoique ce soit, merci de donner les retours suivants :

dkms status
sudo lshw -class network

billgastrik

A la maison, mais là je suis au boulot et je ne vois rien... pas de réseaux extérieurs et mon pc m'annonce "aucun adaptateur trouvé"

#10 édité : merci de donner les retours de commande STP

@Nico

Tu as le github de tomaspinho > Réseaux WIFI détectés sauf le mien [Résolu]

Ou les nouveaux paquets > packages.ubuntu.com/search?keywords=rtl8821ce-dkms

NicoApi73

ok, on va commencer par tout nettoyer :

sudo apt remove rtl8821ce-dkms --purge
sudo dkms remove rtl8821ce/5.2.5.2.1.30816.20190425 --all
sudo dkms remove rtl8821ce/v5.2.5_1.26055.20180108.1 --all
sudo dkms remove rtlwifi-new,/0.6 --all

Puis :

cd
rm -rf rtl8821ce
git clone https://github.com/tomaspinho/rtl8821ce
cd rtl8821ce
make
sudo make install
sudo modprobe 8821ce
sudo lshw -class network
nmcli dev wifi

EDIT : /!\ Merci de donner tous les retours

J'ai l'impression que rien n'a changé...

Effectivement, le driver n'est pas lié à la carte.
Que donne :

sudo modprobe -r 8821ce
sudo modprobe 8821ce
lsmod | sort

Et redonne

sudo lshw -class network

car je t'ai fait déchargé puis recharger le module (au cas où un ancien module était encore chargé...)
