Bonjour,
Mon pc portable lenovo ideapad est en dual boot avec windows 8. Je n'ai pas utilisé le pc depuis 3 mois car les charnières étaient pétées (merci l'obsolescence programmée). Depuis que je les ai changées, ainsi que le capot arrière (qui contient les antennes wifi si je ne me trompe pas ?), je n'arrive pas à faire fonctionner le wifi sur ubuntu, alors que que celui-i marche très bien sur Windows...
J'ai tenté les procédures indiquées sur cette page :
http://doc.ubuntu-fr.org/wifi, mais sans succès.
Voici toutes les infos demandées (
