Mon ordinateur utilise l'ethernet depuis quelques années ; maintenant je voulais utiliser le WiFi et j'ai acheté un dongle USB.
Le dongle a fonctionné sans problème, mais la connexion ne dure qu'une minute environ. Après cela, il n'y a plus d'internet et je ne vois plus aucun SSID.
Je peux réutiliser le dongle pendant une minute en le retirant et en le rebranchant. Mais une minute, c'est beaucoup trop court pour l'utiliser de cette façon...
J'ai désactivé la gestion de l'alimentation USB (je pense) en ajoutant
USB_BLACKLIST="0bda:818b"à /etc/default/tlp mais cela n'a pas aidé.
