Bonjour à tous,
sur mon PC de bureau (Acer Aspire T180 avec clé Wifi Hercules HWGUSB2-54-V2), la mise à jour vers Ubuntu 17.04 fait que le Wi-Fi ne se connecte plus (Freebox Mini-4K). Je précise que j'ai un double boot avec Windows XP et le Wi-Fi fonctionne sous Windows, donc je pense que ni la clé Wifi ni la Freebox ne sont en cause.
La Wi-Fi essaie de se connecter mais n'y arrive jamais. J'avais eu un souci sur mon PC portable au moment du passage à Ubuntu 16.04 =>
https://forum.ubuntu-fr.org/viewtopic.php?id=1988730&p=2
J'ai essayé la même solution mais ça ne fonctionne pas. J'ai donc remis le fichier GRUB tel quel.
Voici les infos nécessaires que j'ai récolté :
