Connexion wifi lente et carte wifi apparaissant sous wlan0/wlan1&wifi0
Bonsoir,
je viens d'installer Ubuntu 8.04 pour la premiere fois sur mon pc mais je rencontre quelques soucis. Pourtant, il semble que ma carte wifi (dongle D-Link dwl-g122 rev C1) soit entierement prise en charge par Heron.
Mais ma connexion est tres lente, ma connectivite faible (50%) alors que je suis a moins de 3m de mon modem et lorsque je tape iwconfig, ma carte apparait 3x sous wlan0, wlan1 et wifi0 avec la meme adresse mac. Enfin, il semble que mon debit soit limite a 11Mbps
Meme si je suis un newby sur Linux, mon petit doigt me dit que tout est lie. Pourriez-vous donc m'aider un peu svp.
Un grand merci par avance en tout cas.
Ci-dessous les details necessaires pour le 1er post
