Réinstaller Bluetooth et Wifi

Floppy

Bonjour à tous,

suite à un récent plantage de mon PC, j'ai du faire une grosse mise à jour pour le rallumer proprement. Pour une étrange raison, je n'ai plus ni wifi, ni bluetooth. J'ai essayé un peu toutes les solutions proposées, mais rien n'en ressort, je suis perdu.

Merci d'avance de votre aide.

Florent

En regardant ce fil > wifi-not-working-on-ubuntu-14-04-amd64-qualcomm-network-qca8172, il est mentionné une carte Broadcom BCM43142.

si l'ordi est récent (moins de 5 ans) regarde la désactivation du secure-boot au § 2 [Tuto] Pas de Wi-fi ? Eléments importants à vérifier et doc juste au début du § 3.

xubu1957

On peut aussi rechercher en bluetooth .Il faut fournir :

uname -a; lspci -nnk | grep -iA2 net; lsusb; dmesg | grep -i bluetooth; dmesg | grep -i firmware; lsmod | grep bluetooth

sudo service bluetooth status

et :

dpkg -l | grep blue

Floppy

Salut xubu,

je viens de comprendre le problème en allant chercher le "secure boot" ; il se trouve que le wireless était désactivé, sans doute suite au bug que j'ai récemment connu. Désolé pour le dérangement, je n'avais pas vérifié avant !
Merci de ton aide !

Florent

Bonjour,

Fais voir :

lspci -k -nn | grep -A 3 -i net

Floppy

Voici :

C'était pas le secure-boot qui bloquait, tu as bien fais d'aller vérifier les options wireless du BIOS !
