Pas de carte wifi sous Ubuntu Résolu/Fermé

Question

Bonjour,

Après avoir acheté un nouveau PC (MSI) freeDOS, j'ai décidé d'installer Ubuntu. Malheureusement celui-ci ne détecte aucun point d'accès Wifi ! 

J'ai essayé d'aller sur divers forums et effectué diverses manip mais sans résultat. Je ne m'y connais pas beaucoup. 

Dans un terminal j'ai tapé: iwconfig et là je n'ai eu que: 
" lo         no wireless extensions. "

J'ai alors tapé: lspci | grep -i net et là j'ai eu:
" 03:00.0 Ethernet controller: Ahteros Communications Inc. Device e091 (rev 13)
  05:00.0 Network controller: Intel Corporation Device 08b3 (rev 83) " 

J'ai lu quelque part que c'était un problème de firmware ou driver, 

Quelqu'un pourrait il m'aider à faire fonctionner ma carte wifi ??

Merci d'avance pour vos réponses

Bonjour,

Essaies avec une distrib Debian.

Salut,

Ouvre un terminal et tape les 2 commandes suivantes (l'une après l'autre, la 1ère ne retournant rien comme résultat) :

sudo update-pciidslspci -vnn

Regarde du côté des firmwares; sous Debian Jessie
johand@osiris: ~ $ apt-cache search atheros | grep firmwarefirmware-linux-free - Binary firmware for various drivers in the Linux kernelfirmware-atheros - Binary firmware for Aatherostheros wireless cardsfirmware-zd1211 - binary firmware for the zd1211rw wireless driver
Sous Ubuntu, tu devrais obtenir un résultat similaire, d'où une piste
sudo apt-get install firmware-atheros
Que donne un dmesg | grep -i atheros ou une variation de cette commande ?

Merci pour vos réponses @zipe31 : J'ai bien tapé les commandes indiquées. La 1ère ne m'a rien donné comme prévu et la 2ème m'a donné le texte suivant : pilou@Pilou:~$ lspci -vnn00:00.0 Host bridge [0600]: Intel Corporation Haswell DRAM Controller [8086:0c04] (rev 06) Subsystem: Micro-Star International Co., Ltd.
