Bonjour,
Merci pour ta réponse rapide. J'ai toujours le problème, malgré les actions suivantes :
- essai de réglages des antennes : niveau de signal identique pour les deux donc je n'ai pas fait de modif (cf trace plus bas)
- blacklistage des modules acer-wmi et ideapad_laptop puis redémarrage :
dom@Packard-ENLG71BM:~$ cat /etc/modprobe.d/blacklist-acer-wmi.conf
# ajout pour essayer de faire marcher le wifi, suite upgrade vers 18.04
blacklist acer-wmi
dom@Packard-ENLG71BM:~$
dom@Packard-ENLG71BM:~$ cat /etc/modprobe.d/blacklist-ideapad.conf
# ajout pour regler pb de wifi suite upgrade 18.04
blacklist ideapad_laptop
voici le résultat de bootctl et autres commandes utiles (j'ai refait un wificheck)
