RTL8821CE / Plus de wifi

xubu1957

@Nico

Je ne pense pas.

Dans le lien fourni au #78, c'était le passage par un ancien commit.

Le RTL8821CE est arrivé dans les dépôts > ubuntuupdates.org/package/core/bionic/universe/updates/rtl8821ce et rtl8821ce-dkms, pour remplacer le github de tomaspinho.

NicoApi73

Je n'ai pas le courage de reprendre tout le fil, quel est le pilote actuellement installé?

billgastrik

NicoApi73 a écrit@billgastrik : merci de regarder le #76. Sans ça nous ne pouvons savoir si les commandes sont bien passées.

> quelle commande je dois taper, précisément ?

NicoApi73

Tu cliques sur le lien donné dans le #76, tu lis le contenu et dorénavant quand tu nous donnes un retour de commande, tu appliques ce qui est préconisé par moko138.

Quand je vois le retour suivant :

modprobe: FATAL: Module rtl8821ceiwconfig not found in directory /lib/modules/5.3.0-40-generic

ça veut dire que tu as tapé n'importe quoi avant !

Nous passons du temps pour essayer de te dépanner et l'absence de ces informations nous fait perdre du temps. Merci de le comprendre.

EDIT : le n'importe quoi en question est probablement quelque chose du genre :

sudo modprobe rtl8821ceiwconfig

xubu1957

Donne :

sudo modprobe -r 8821ce

sudo modprobe 8821ce

iwconfig

Le 29/03/2018, moko138 a écrit Un retour complet doit contenir toutes les lignes,
depuis celle, entière, de la commande
jusqu'à la ligne attendant la commande suivante, exemple :
moi@mon-pc~$: ma-commande
son retour
moi@mon-pc~$:
Faute de quoi, il manque souvent à ceux qui tentent de t'aider des éléments essentiels.

(Plus de détails dans ce message-ci Retour utilisable de commande.)

Et si tu ne veux pas divulguer ton nom d'user, tu le remplaces par "toto" ou ce que tu veux.

ok, j'ai relu le post. Fais ce qui suit et dis moi si ça fonctionne. Si c'est le cas, il y aura encore des choses à faire :

sudo modprobe -r rtl8821ce
cd ~/rtl8821ce
make
sudo make install
sudo modprobe 8821ce
lsmod | sort
sudo lshw -class network
nmcli dev wifi

billgastrik

Ca a l'air de fonctionner mais avec un signal très faible.(enfin, l'icone dit que le signal est faible, mais j'ai l'impression que ça tourne pas si mal...)
