Mon wifi se traine, comment mieux configurer?
Salut, j'ai un petit problème, mon wifi se traîne, au lieu d'avoir un débit max de 54mb/s, j'ai au mieux 24mb/s (ce qui est mieux que rien), voire 1mb/s (ce qui est moins que rien) . J'aimerais pouvoir utiliser au moins l'un de mes wifi au maximum de ses capacités. Pour le débit de 1mb, ça vient de ralink rt2500, bug enregistré sur launchpad il me semble (y a plus qu'à attendre le patch? ), par contre je ne comprends pas pourquoi le dongle sagem de la livebox plafonne à 24 mb (modèle xg760A) .Ça vient de quoi? Du réglage livebox? Du wpa? Un réglage dans linux? Autre chose? J'attends vos suggestions, merci d'avance!
Quelques infos sur ma config:
Ubuntu Hardy
2.6.24-15-generic i686
Livebox sagem

Re : Mon wifi se traine, comment mieux configurer?
http://fr.wikipedia.org/wiki/Wifi
norme g (de wifi g) :
54 Mbit/s théoriques soit environ 25 Mbit/s rééls
voilà
sinon recemment il y a un autre fai (free) qui integre la norme n du wifi (300 Mbits/s theorique)

Re : Mon wifi se traine, comment mieux configurer?
Donc ce serait normal... C'est quand même bizarre de mélanger ainsi le débit théorique et réel dans la config elle même!
