[Résolu] [Xubuntu] Signale wifi très faible/inexistant
Bonjour a tous, je vous explique mon problème.
Je viens de finir l'installation en dual boot avec Windows 10, Sur Windows je capte ma wifi parfaitement. Mais une fois passer sur xubuntu , mon signale wifi apparaît 1 fois sur 20 et impossible de se connecter dessus. Actuellement je me connecte grâce a un partage de connexion avec mon téléphone, j'ai donc fais un wificheck même si je ne suis pas connecter sur le bon réseaux (je ne sais pas si c'est utile mais on ne sait jamais !)
