Bonjour à tous,
J'ai tout fraichement installé la dernière version d'ubuntu sur un pc portable.
Au premier démarrage le WiFi n'étais pas disponible, il ne l'étais pas non plus lorsque j'avais installé un debian
l'année dernière mais j'avais finallement réussi à installer les drivers. En revanche cette fois-ci...
J'ai fais beaucoup de manip et certaines sont peut-être inutile, toujours est-il que je n'ai pas de WiFi 🙁(
Je précise que je suis pas un expert (du tout) en Linux 🙂
Merci d'avance si vous choisissez de m'aider 🙂
Voici quelques informations à propos de mon système :

Ma carte réseau, que j'ai beau enable, se disable à chaque reboot, et ça ne résoud pas cette histoire de WiFi même up
Il s'agit donc de BCM43142
J'ai installé les drivers avec synaptic:
- broadcom-sta-common
- broadcom-sta-dkms
- broadcom-sta-source
lshw -C network
