Lenteur wifi avec Hercule HWGUSB2-54-LB

Bonjour,

Je suis sous Kubuntu 10.10 - 64 bits, installation toute fraiche.

uname -r -m
2.6.35-27-generic x86_64

Le signal est excellent et la connexion wifi fonctionne, mais mal, que ce soit pour les téléchargements de paquets ou la navigation sous konqueror et firefox, avec des pings mauvais et des pertes de paquets :

--- www.l.google.com ping statistics ---
26 packets transmitted, 18 received, 30% packet loss, time 52329ms
rtt min/avg/max/mdev = 50.518/360.765/1096.618/391.862 ms, pipe 2

J'ai tenté suite à divers post :
- le reboot de ma freebox (une vieille, version 4 je crois, cf zone non dégroupée) ; une carte pcmcia linksys w54g est insérée dedans. Pas de problème de wifi avec les autres ordi / téléphones de la maison.
- le passage à wicd au lieu de KDE network manager
- la désactivation de l'IPv6
... mais sans succès

les infos indispensables :

Je n'ai pas tenté ndiswrapper, ne trouvant que des pilotes en .exe et pas de fichier .inf.

Toute aide sera la bienvenue ! Merci d'avance.
