Une configuration wifi sur Debian avec madwifi et ath0 sur un portable Acer Aspire 5720Z présente une incapacité à obtenir une adresse IP via DHCP et des difficultés d’accès au réseau sans fil eXo_Home.
Les commandes montrent une interface ath0 non associée au point d’accès et des adresses locales 169.254.x.x, avec une passerelle par défaut sur 192.168.1.1 via eth0, ce qui empêche le wifi d’être opérationnel.
Plusieurs interventions évoquent l’usage de wpa_supplicant pour WPA-PSK et des ajustements dans /etc/network/interfaces, notamment l’activation de wireless_mode et du canal, mais aucune solution homogène n’a été instaurée.
En tant que piste, certaines suggestions remettent en cause le mode opératoire et recommandent d’essayer ‘wireless_mode managed’ et ‘wireless_channel’ dans wpa_supplicant.conf pour stabiliser l’association réseau.
quand jai taper:
sudo ifconfig ath0 up
sudo dhclient ath0
ca ma donné ca :
exo:/home/exo# dhclient ath0
There is already a pid file /var/run/dhclient.pid with pid 11143
killed old client process, removed PID file

donc c'est la qui ya un beug.
dhclient ath0
on devrai avoir par exemple ca:

Il faut que tu charge les headers correspondant à ton noyau (ex: linux-headers-2.6.....), le paquet de fichier source linux (ex : linux-source-2.6......) . Normalement le compilateur GCC est installé.
Pour connaitre ta version de linux : uname -r
