[Résolu] ma carte RTL8188CE ne voit plus de réseau sans fil
Bonjour
J'arrive à un endroit où je vais régulièrement, et je ne peux me connecter au réseau sans fil, vu que je ne le vois pas.
Mon téléphone, par exemple, le voit et s'y connecte bien (Freebox V4)
Quelques infos dans le syslog

Re : [Résolu] ma carte RTL8188CE ne voit plus de réseau sans fil
J'ai redémarré un vieil ordinateur, et
iwlist wlan0 scan
ne voit rien, donc je me demande si cela n'est pas lié à la nouvelle Freebox v4, qui a remplacé une vielle Freebox V4 avec une carte wifi amovaible.
Ce qui est bizarre, c'est que mon ordinateur a capté le wifi ici il y a quelque temps avec la nouvelle Freebox v4.
Etrange.

Re : [Résolu] ma carte RTL8188CE ne voit plus de réseau sans fil
Bon on dirait que c'est un problème de Freebox, je viens de tester avec le CD du dernier Linux Pratique, Fedora 16 Security, pas de wifi vu.

Re : [Résolu] ma carte RTL8188CE ne voit plus de réseau sans fil
Ici c'est vraiment la cambrousse, il n'y a aucun réseau wifi autour
Edit : J'ai vérifié, mon wifi est bien sur le canal 11
J'ai changé sur la Freebox, mis un wep, j'ai pu me connecter un certain temps, puis plus du tout.
J'ai rebooté sous Windows un PC qui se connecte à Internet sans problème.
Je vais changer nouveau et mettre un WPA sur la box et retester.
Bizarre tout ça.

Re : [Résolu] ma carte RTL8188CE ne voit plus de réseau sans fil
Merci pour les infos.
Bizarrement le problème a disparu. Je ferai tes modifs si cela revient.
J'hésite entre un bug de la Freebox et un bug du wifi.
