Edgy et madwifi
J'ai installé edgy 6.10 sur ma machine (Dell p3 500Mhz), je dois la faire fonctionner avec une carte sans fil (arg5005) qui passe par un routeur D-Link DI-524 pour accéder à l'internet.
Mon edgy est à jour avec le nouveau noyau. J'ai utilisé madwifi et network-manager. Pour l'instant, tout semble fonctionner. Mais ma connexion reste faible (entre 5% et 17%).
Est-ce qu'il existe une façon d'augmenter cette performance? Car ma connexion est parfois instable et j'aimerais la renforcer davantage, merci d'avance pour vos lumières, à +,
