Bonjour
Sur un PC portable HP tout neuf avec Ubuntu (Mate) 18.04, je ne trouve pas de wifi.
Quand il avait W*** préinstallé, le wifi était fonctionnel, donc je ne pense pas que ce soit un problème matériel, mais j'ai complètement reformaté.
J'ai trouvé des infos sur
https://askubuntu.com/questions/1047245/wifi-adapter-not-found-in-ubuntu-18-04 mais elle renvoie à un autre fil, où il est indiqué une solution dont on est averti qu'elle ne fonctionne pas sous 18.04...
D'autre part, je n'ai pas d'autre connexion internet possible. Ici et maintenant je n'ai pas de quoi me raccorder en RJ45, mais de toutes façons la plupart des nouvelles machines n'ont plus ce type de connecteur. Est-ce qu'il y aurait un autre moyen en utilisant un smartphone ?
en cas de besoin, voici le retour de "wificheck"
Merci pour votre aide !
