Bizarre, très bizarre...
Tu as quoi comme carte wifi ?
j'ai un dongle livré avec la neuf box.voici ce que donne lsusb:
Bus 001 Device 005: ID 1058:0403 Western Digital Technologies, Inc.
Bus 001 Device 002: ID 0cde:0008 Z-Com
Bus 001 Device 001: ID 0000:0000
Bus 004 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 002: ID 062a:0102 Creative Labs
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000

donc visiblement ce serait Z-com le chipset.
A savoir que sous F7 ca fonctionnait bien ainsi que sur la première install de la F8
Que renvoie en root la commande suivante ?
ndiswrapper -l
(moyen simple de savoir si ta carte est supportée par le noyau ou pas ^^).
oui je l'avais deja verifié:
wlanuig : driver installed
device (0CDE:0008) present (alternate driver: p54usb)
device (0CDE:0008) present (alternate driver: p54usb)
Ta clé est déjà supportée par le noyau Linux !
Il y a sans doute un conflit de modules entre ndiswrapper et p54usb, ce qui expliquerait que ta clé ne fonctionne pas.

1- Désinstalle NdisWrapper et vire ses fichiers de conf. :
# yum remove kmod-ndiswrapper ndiswrapper
# rm /etc/modprobe.d/ndiswrapper
2- Installe le firmware de ta clé :
# wget  http://prism54.org/firmware/2.5.8.0.arm
# mv 2.5.8.0.arm  /lib/firmware/isl3887usb_bare
3- Reboot !
je viens de faire les modifications que tu m'as indiquées mais je n'ai plus de trace de sans fil désormais
je n'ai plus d'interface sans fil detectée et NetworkManager ne m'indique plus de connexion sans fil
par contre le pilote a du se charger car la clé est allumée
Le centre de contrôle de kde me dit qu'il ne peut pas detecter automatiquement l'interface. Faut il que je rentre le nom del'interface à la main si oui est ce que ce serait quelque chose du style wlan0?
iwconfig me retourne ceci:

lo no wireless extensions.

eth0 no wireless extensions.
Que renvoient les commandes suivantes ?

merci pour ton aide en tout cas...
Le problème est simple (heureusement) : le firmware ne porte pas le bon nom !
La police d'écriture est telle qu'on ne distingue que très mal le chiffre un « 1 » de la lettre « L » en minuscules :
is13887usb_bare (incorrecte)
? isl3887usb_bare (correct)
On va le renommer :
# cd /lib/firmware
# mv is13887usb_bare isl3887usb_bare
Puis recharger le module :
# rmmod p64usb
# modprobe p64usb
Je pense que ça devrait aller mieux ainsi.
:-D génial ca fonctionne parfaitement.
merci mille fois. je suis rééllement impressionné par la maîtrise que vous tous possédez de ce système.
