oui, c'est normal..

normalement, ta carte ethernet est reconnue en eth0 et le carte wifi en eth1;-)
tu peux poster la sortie de

eh bien tout va bien..8-)
tu n'as plus qu'à faire:
# modprobe ipw3945
# chkconfig --level 345 ipw3945 on
# chkconfig --level 345 NetworkManager on
# chkconfig --level 345 NetworkManagerDispatcher on
# service ipw3945 start ; service NetworkManager start ; service NetworkManagerDispatcher start
et là tu auras une appli qui (en haut à droite sous gnome) qui te permettra de choisir ton réseau, entrer ta clé wep, te connecter,... etc:-D:-D

edit: post aussi un "# iwlist scan ", et pense à mettre ta clé en format wep!!

bon, si je ne me trompe pas, au départ tu as essayé de charger les paquets et de les installer manuellement?
tu as aussi essayé d'installer le paquet "ieee80211"?

tu doit retirer les paquets ieee80211 que tu as installé au début:
pour les identifier: 
# rpm -qa | grep -i ieee80211
puis tu les désinstalle avec:
# rpm -e "nom du paquet"
(il doit y'en avoir deux..."kmod-ieee80211-1.2.16-1.2.6.19_1.2895.fc6.i686.rpm" et "ieee80211-1.2.16-1.kwizart.fc6.noarch.rpm" si je ne me trompe pas)

tu retires le module de ta carte:
# yum remove kmod-ipw3945.i686
puis, tu vérifies la version de ton noyau:
# uname -r
si ce n'est pas "2.6.20-1.2933.fc6" qui sors, tu fait un yum update, et tu redémarres sur le nouveau noyau..et pour finir, tu refait 
# yum install kmod-ipw3945.i686
ps: à tout hasard, même si le noyau est le bon, tu peux faire un yum update qd même.. ca ne peut pas faire de mal...
si ca ne marche pas, ce qui est fort possible, je laisse la main...
il n'y a plus qu'à attendre que notre cher Pikachu ou Mr Kwizart passe dans le coin et voient ton fil...😉
@TNinFR
tu as fait make uninstall ? pour ieee80211 et ipw3945 avant d'installer le module par rpm?
tu as fait make uninstall ? pour ieee80211 et ipw3945 avant d'installer le module par rpm?
je ne crois pas qu'il ait compilé quoique ce soit.. apparement, il a installé directement avec les rpm..

cf le post #13:
[root@localhost methodeyum]# rpm -ivh ieee80211-1.2.16-1.kwizart.fc6.noarch.rpm ipw3945-1.2.0-1.kwizart.fc6.noarch.rpm ipw3945d-1.7.22-1.kwizart.fc6.i686.rpm ipw3945-ucode-1.14.2-1.kwizart.fc6.noarch.rpm kmod-ieee80211-1.2.16-1.2.6.19_1.2895.fc6.i686.rpm kmod-ipw3945-1.2.0-1.2.6.19_1.2895.fc6.i686.rpm mkinitrd-5.1.19.0.2-1.i386.rpm kernel-2.6.19-1.2895.fc6.i686.rpm
c'est pour ca que je suis étonné de voir ieee80211, car j'avais compris que les rpm n'était plus dispo...
J'ai du rater un épisode...:hammer:
non je n'ai pas fait make uninstall
[root@localhost ~]# rpm -qa | grep -i ieee80211
[root@localhost ~]#
donc si tu fais make uninstall dans chaque répertoire ieee80211 et ipw3945 cela donne quoi ?
Fait eventuellement apres :
su -
rmmod ieee80211
rmmod ipw3945
depmod -ae
modprobe ieee80211
modprobe ipw3945
dmesg |grep ieee
dmesg |grep ipw ?

tu as cassé ton kernel en voulant installer le ieee80211...
IL faut le réinstaller...
Reboot sur le kernel le plus ancien et fait:
su -
yum remove kmod-ipw3945
rpm -qa kernel*
rpm -e kernel-2.6.20-1.2933.fc6 (et tout les kernel 2933)
yum --enablerepo=kwizart install kmod-ipw3945.i686
chkconfig --level 35 ipw3945 on
Reboot sur le kernel nouvellement installé...
En rebootant sur l'ancien kernel...Ma carte ethernet n'est plus reconnu...donc impossible d'utiliser yum
