Bonjour.
J'ai installé, en dual boot, Lubuntu 18.04 sur un ordi portable HP 15-db0035nf et je n'arrive pas à avoir de wifi. J'ai installé plusieurs versions de la distribution Ubuntu (Lubuntu 18.04, Ubuntu 18.04 et Lubuntu 18.10). Pour le moment j'en suis à une Lubuntu 18.04 LTS toute neuve, juste les mises à jour suivant l'installation.
Auparavant, j'ai parcouru le forum et tenté les manipulations proposée mais en vain. Je suppose que la solution donnée est pour une autre carte wifi.
Ci-dessous le résultat du script wificheck de framagit.
