Salut à tous
depuis ma récente installation de la 18.04 sur laptop Lenovo Legion Y520 , j ai un énorme soucis de stabilité de ma connexion Wifi ( connexion via Samsung S5 chez free )
en effet , je suis très souvent obligé de relancer la connexion ( deconnecter/connecter ) afin de pouvoir surfer sans quoi il est parfois impossible d'atteindre la toile et ce à plusieurs reprises au cour de la journée et sans forcement de délai régulier
voici quelques infos pour ceux qui pourraient éventuellement me donner un coup de pouce :
azrael@azrael-Y520:~$ iwconfig
