Pb connexion Wifi Lenovo G50-30 s'arrête après Ubunto 14.04 [RÉSOLU]
Bonsoir,
J'ai un soucis avec ma connexion wifi. J'ai un lenovo G50-30 sous ubuntu 14.04. J'arrive à me connecter à ma wifi lorsque j'allume mon pc, puis au bout de quelques temps ou lorsque je le mets en veille, la wifi ne fonctionne plus.
J'ai fait le tour des problèmes similaires sur le forum et j'ai essayé quelques solutions en vain.
Voici mon diagnostic :
