Wifi fonctionnement aléatoire
Bonjour,
Je viens de me lancer avec Ubuntu. Tout marche bien, sauf la connection Wifi qui marche "quelque fois", sans que j'ai pu identifier des causes.
J'ai par ailleurs lu quelques tutoriels : le pilote de ma carte est installé, le matériel reconnu... et ça ne marche pas. Quelque fois j'ai la connection, la plupart du temps non.
La connection filaire, par contre, marche nickel!
Quelqu'un a-t-il une suggestion ?
Merci
(voir ci-dessous l'état de mon installation)
Carte WIFI PCMCIA Linksys WPC54G ver. 3.1
Pilote : isbcmnds

Re : Wifi fonctionnement aléatoire
bonjour
Si tu utilises les drivers initiaux de Hardy, ils ne sont pas au meilleur de leur forme.
Tu devrais tenter directement cette méthode

Re : Wifi fonctionnement aléatoire
Le problème est résolu... mais pas comme indiqué dans le tuto.
Après avoir (péniblement : je suis très débutant) chargé, compilé, s'être énervé... ça ne marche toujours pas.
J'ai craqué : j'ai changé ma carte wifi pour une D-Link DWL-G650 (29€ rue de Charenton Paris 12)
Pas techniquement satisfaisant mais efficace. Ça marche maintenant.
