 Posted: Mon Mar 16, 2009 9:13 am Post subject: prism54 e wpa_supplicant [RISOLTO] |
 |
|
Salve, su un pc qui a casa, la scheda pcmcia wifi (una Zyxel G100) ha smesso di funzionare da un po' e sto cercando di ripristinare (con poco successo) una condizione funzionante.
Ora premetto che non ho capito molto come stanno ristrutturando il kernel per quanto riguarda mac80211 e softmac ma andiamo per ordine e vi dico come sta configurato il tutto.
attualmente nel kernel (gentoo-sources-2.6.27-r8 ) ho queste voci abilitate:
| Code: | CONFIG_WIRELESS_EXT=y
CONFIG_WIRELESS_EXT_SYSFS=y
CONFIG_CFG80211=m
CONFIG_NL80211=y
CONFIG_MAC80211=m
CONFIG_MAC80211_RC_PID=y
CONFIG_MAC80211_RC_DEFAULT_PID=y
CONFIG_MAC80211_RC_DEFAULT="pid"
CONFIG_IEEE80211=m
CONFIG_IEEE80211_CRYPT_WEP=m
CONFIG_IEEE80211_CRYPT_CCMP=m
CONFIG_IEEE80211_CRYPT_TKIP=m
CONFIG_WLAN_80211=y
CONFIG_PRISM54=m
CONFIG_P54_COMMON=m
CONFIG_P54_USB=m
CONFIG_P54_PCI=m |
lsmod mi dice:
| Code: | Module Size Used by
prism54 51336 0
p54pci 9472 0
p54common 10880 1 p54pci
mac80211 131852 2 p54pci,p54common
cfg80211 22792 1 mac80211 |
e lspci mi dice che usa prism54 e vabé
| Code: | 03:00.0 Network controller: Intersil Corporation ISL3890 [Prism GT/Prism Duette]/ISL3886 [Prism Javelin/Prism Xbow] (rev 01)
Subsystem: Tekram Technology Co.,Ltd. ALLNET ALL0271 Wireless PCI Adapter
Flags: bus master, medium devsel, latency 80, IRQ 11
Memory at 58000000 (32-bit, non-prefetchable) [size=8K]
Capabilities: [dc] Power Management version 1
Kernel driver in use: prism54
Kernel modules: p54pci, prism54 |
ora
wpa_supplicant è configurato in maniera banale (sul mio portatile con ipw2200 la stessa conf funziona)
| /etc/conf.d/net: | config_eth1=( "dhcp" )
modules_eth1="wpa_supplicant"
wpa_supplicant_eth1="-Dprism54 -c/etc/wpa_supplicant/wpa_supplicant.conf" |
| /etc/wpa_supplicant/wpa_supplicant.conf: | ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel
network={
key_mgmt=NONE
priority=-9999999
}
network={
ssid="xy"
proto=WPA
key_mgmt=WPA-PSK
pairwise=TKIP
psk="password"
priority=2
} |
ora però qui lanciando wpa_supplicant da console sembra che l'associazione vada in timeout e non so come risolvere:
| Code: | # wpa_supplicant -i eth1 -c/etc/wpa_supplicant/wpa_supplicant.conf -dd -Dprism54

suggerimenti e consigli sempre ben accetti!!!
sarei anche interessato ad abbandonare la vecchia struttura kernel, ma sinceramente sono un po' titubante a riguardo.

Non ho assolutamente idea, poiché uso iwl con soddisfazione.
Ma visto che qui c'è carenza di idee la butto li... provato ad usare -Dwext al posto di -Dprism54 ?
Altro consiglio a mo' di rito voodoo che ti posso dare è di provare a vedere nel file di configurazione di wpa_supplicant di variare
la variabile "scan_ssid=1" a "scan_ssid=0" o viceversa. Ora non ricordo i dettagli, ma mi ricordo bene che una volta ho risolto in questo modo.
Mah...
