toutafai · Le 02/01/2014, à 22:48

salut,

Essaye en changeant de canal wifi (ne pas oublier d'enregistrer les changements et de rebooter la livebox apres)

Diop93 · Le 02/01/2014, à 23:07

comment on fait pour cela parce que même prés du wifi j'ai que 2 barre

toutafai · Le 02/01/2014, à 23:48

cela depent de ton modele de box (voit la doc sur le site du fai), mais cela se passe à l'adresse 192.168.0.1 ou 192.168.1.1

il n'est pas possible d'augmenter le dbm ou le signal level je suis à -75 dbm là oubien

toutafai · Le 05/01/2014, à 01:27

pas a ma connaissance (mais je connais pas tous). Apres il y a d'autre paramètre sur lesquelle ont peu "joué" facilement...la aussi cela se passe dans l'interfaces d'administration de la livebox

Diop93 · Le 12/01/2014, à 16:25

d'accord donc il n'est pas possible aussi de télécharger un pilote wifi

f.x0 · Le 12/01/2014, à 17:08

Tu peux par contre essayer ceci :

sudo apt-get remove --purge bcmwl-kernel-source

sudo rmmod iwl3945

sudo modprobe iwl3945 disable_hw_scan=1

testes le wifi, si cela est mieux,
Il faut rendre la commande permanente

gksudo gedit /etc/modprobe.d/iwl3945.conf

une page blanche s'ouvre, écris cette ligne

options iwl3945 disable_hw_scan=1

enregistres et quittes gedit

testes le wifi,
si ce n'est pas mieux tapes

gksudo gedit /etc/modprobe.d/iwl3945.conf

modifies le fichier en ajoutant une ligne comme ceci :

alias wlan0 iwl3945
options iwl3945 disable_hw_scan=1

enregistres et quittes gedit

sudo reboot

Ensuite testes le wifi, c'est OK ???

puis tapes

cat /etc/modprobe.d/iwl3945.conf

Bonsoir,

essaye en ne laissant que la ligne suivante dans le fichier /etc/modprobe.d/iwl3945.conf :

options iwl3945 disable_hw_scan=1

enregistre, reboot et re test

PS : tu as essayé en changeant de canal wifi ?
