Bjr,

J'ai une carte wifi dans mon portable Dell 1520:
Quote:
0c:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)


j'utilise le drivers iwl3945 integré dans le kernel 2.6.26.5, et je rencontre d'enormes instabilitées:

je n'ai aucun cryptage, juste un ssid non broadcast, et un filtrage d address mac sur mon router linksys wrt54gs ( tomato firmware 1.21 )... donc franchement je peux pas plus simplifier la vie au driver :x

1/ j'ai un script de connection:
Quote:
rmmod iwl3945 mac80211 cfg80211 ; modprobe iwl3945 ; iwconfig wlan0 channel 2 rate 54M mode Managed essid 'SSID' ap 00:13:10:15:3A:86 ; rm /var/run/dhcpcd-wlan0.pid ; dhcpcd wlan0


je suis obligé de le lancer une bonne disaine de fois avant qu'il se racroche à mon router... sinon il reste sur :
Quote:
jerem-laptop jerem # sh iwl_script2
ERROR: Module cfg80211 does not exist in /proc/modules
rm: cannot remove `/var/run/dhcpcd-wlan0.pid': No such file or directory
wlan0: dhcpcd 4.0.2 starting
wlan0: waiting for carrier
wlan0: carrier acquired



2/ ma connection se decroche de facon aleatoire ( toute les 5 minutes à 1h )
dmesg:
Quote:
wlan0: No ProbeResp from current AP 00:13:10:15:3a:86 - assume out of range


c'est vraiment l'enfer...

quelqu'un a des astuces pour ameliorer mon cas ?


merci

Utiliser wpa_supplicant, et par les scripts d'init Gentoo, pour automatiser les connexions/reconnexions :)
