[Résolu] Probléme wifi lent
Bonjour, je suis depuis quelques jours passer sous xubuntu 12.10 à la place de windows xp sur un compaq presario c500.
La carte wifi est une broadcom b4311, et bien entendu, comme plein de monde, j'ai eu des tas de soucis avec...
J'ai testé des tas de solution qui sont proposé sur ce forum qui n'ont pas marché, mais j'ai reussi à la faire marcher grace à ce package : lien
Or maintenant le wifi fonctionne mais est extremement lent...
Je sais plus du tout quoi faire alors je fais appel à votre communauté, pouvez vous m'aidez ?
Je suis à deux doigts de repasser sous windows
