Bonjour à tous, alors voila je viens d'installer UBUNTU 16.04 sur mon ordinateur. C'est un DELL INSPIRON 1545. Depuis l'installation je n'arrive pas à avoir de wi-fi, pourtant celui-ci marchait parfaitement sous Windows 7.
De plus je n'y connais vraiment rien. Donc j'ai lu beaucoup de choses sur les forums mais s'en résolution de mon problème.
Je vous joins le document wificheck si j'ai bien tout compris. Merci d'avance pour votre aide.
