problème de wifi (activation du wifi sous ubuntu)
Bonjour,
J'ai récemment installé ubuntu sur mon pc tout en gardant vista. Cependant, le wifi ne fonctionne pas sous ubuntu, je peux seulement me connecter à l'aide d'un cable ethernet.
Alors que le wifi est activé sous vista (lumière bleue), il ne s'active pas sous ubuntu (lumière orange) et donc je ne reçois aucun réseau sans fil. Je me demande s'il faut installer quelque chose pour que ubuntu accepte le wifi ?
Mon pc est un HP Pavillon dv6000

Re : problème de wifi (activation du wifi sous ubuntu)
Je débute tout juste sur ubuntu, je ne vois pas trop comment faire. J'ai déja essayer de rentrer une connection sans fil dans le NetworkManager mais comme l'activation wifi ne s'enclenche pas sur ubuntu, je ne parviens pas à me connecter.

Re : problème de wifi (activation du wifi sous ubuntu)
as tu installer le pilote proprio pour ta carte?
menu
Système->Administration->Pilotes de périphériques
Coche
Broadcom B43 wireless driver
Accepte l'extraction du microcode
PS: a faire avec une connexion filaire (le pilote est télécharger automatiquement, donc
connexion obligatoire!)
