pb connexion wifi.
Bonsoir,
Depuis pas mal de temps, j'essaye de résoudre un problème récurrent :
utiliser une connexion wifi gérée par NetworkManager.
En effet, lors de mise à jour de la version Sid, je dois procéder à
plusieurs initialisations de la carte pour que le processus arrive à son
terme.
La version du noyau est : 2.6.32-5-amd64 x86_64.
La commande lspci me donne :

J'ai ajouté la directive suivante au fichier /etc/inittab :
adsl:2345:respawn:/usr/sbin/pppd call dsl-provider.
Mais il semblerait que celle-ci ne puisse pas agir sur le phénomène de
coupure du wifi.
Les archives de la liste me laisse entendre qu'il est préférable
d'utiliser wicd, mais j'aimerais tout de même utiliser dans de meilleure
condition l'utilitaire du bureau Kde.
D'avance merci.
Michaël
