Bonsoir à tous,
Je suis sur lubuntu 20.04, sur une vielle tour récupérée (destinée à la benne) dans une école. Cependant, j'ai un pépin : en dépit de mes efforts, je n'arrive pas à faire fonctionner la petite clé wifi que je lui ai placée dans un port usb --> pas de wifi
j'ai donc tenté de savoir s'il la voyait et là : surprise !
