C'est la première fois que je poste ici et je tiens à vous remercier d'avance pour votre temps :).
Bon, je vais donc essayer de décrire mon problème... J'utilise actuellement Kubuntu 12.04 LTS sur un ordinateur portable Toshiba. J'ai une carte sans fil interne Realtek RTL8723AE pour laquelle j'ai construit et installé les pilotes pour mon noyau et qui fonctionnait bien jusqu'à présent. J'ai également une carte sans fil externe TP-LINK TL-WN722N qui était autodétectée par le système jusqu'à présent sans aucun problème. Cette carte a un chipset Atheros.
Aussi étrange que cela puisse paraître, mes problèmes ont commencé après avoir utilisé la carte TP-LINK sur une machine Windows 7. Après l'avoir fait fonctionner - en installant les pilotes, etc. - je l'ai retirée et suis allé l'utiliser à nouveau sur mon ordinateur portable. Je ne peux pas expliquer pourquoi, mais elle ne fonctionnait plus. Il n'est pas du tout reconnu par le système. Je n'ai certainement rien fait de stupide entre-temps. J'ai alors pensé "ce doit être une malédiction de Bill Gates". Je veux dire, j'ai essayé de ne pas être supersitieux etc, mais je n'ai toujours pas trouvé d'explication plus raisonnable.
Quoi qu'il en soit, j'ai commencé à chercher sur Internet et j'ai trouvé quelques réponses relatives à cette carte. J'ai essayé certaines d'entre elles, mais elles n'ont pas fonctionné. Le dernier essai que j'ai fait était ce post aquí . Après avoir fait cela, j'ai redémarré l'ordinateur portable. Lorsque mon système d'exploitation s'est chargé, je n'ai pas pu voir la carte dans mon gestionnaire de réseau (comme après la "malédiction de Bill Gates"), mais maintenant ma carte interne avait également disparu... J'ai essayé de réinstaller ses pilotes mais rien ne s'est passé... Voilà où j'en suis maintenant. Je ne sais pas vraiment quoi faire. Toute aide sera grandement appréciée :).
(L'anglais n'est pas ma langue maternelle, veuillez donc excuser toute erreur)
