Instalei o gentoo 2007.0 em meu notebook Centrino D520 , que possui a placa wi-fi intel 3945ABG. Segui as recomendações do site do gentoo, wireless networking, mas toda vez que tento me associar, com o comando mostrado, ao AP surge a mensagem:

Code:
localhost ~ # wpa_supplicant -Dwext -i eth2 -c /etc/wpa_supplicant/wpa_supplicant.conf
Trying to associate with 00:19:5b:bc:1d:19 (SSID='HCCT' freq=2457 MHz)
Authentication with 00:00:00:00:00:00 timed out.


O meu arquivo /etc/conf.d/net está assim:

Code:
# This blank configuration will automatically use DHCP for any net.*
# scripts in /etc/init.d.  To create a more complete configuration,
# please review /etc/conf.d/net.example and save your configuration
# in /etc/conf.d/net (this file :]!).
config_eth0=( "dhcp" )
dhcp_eth0="nodns nontp nonis"

config_eth2=( "dhcp" )
dhcp_eth2="nodns nontp nonis"

# Prefer wpa_supplicant over wireless-tools
modules=( "wpa_supplicant" )

# It's important that we tell wpa_supplicant which driver we should
# be using as it's not very good at guessing yet
wpa_supplicant_eth2="-Dwext"
wpa_timeout_eth2=60


O meu arquivo /etc/wpa_supplicant/wpa_supplicant.conf está desse modo:
Code:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
ap_scan=1
update_config=0
fast_reauth=1
eapol_version=1

# Only WPA-PSK is used. Any valid cipher combination is accepted
network={
  ssid="HCCT"
  proto=WPA
  key_mgmt=WPA-PSK
  pairwise=CCMP TKIP
  group=CCMP TKIP WEP104 WEP40
  psk=035e28af879d121c3249601852000a2c2adefe61d48fcd904c8030e21ed3bee9
  priority=2
}


Resultado do iwconfig:
Code:
localhost ~ # iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

eth1      no wireless extensions.

sit0      no wireless extensions.

irlan0    no wireless extensions.

eth2      unassociated  ESSID:"HCCT"
          Mode:Managed  Frequency=2.457 GHz  Access Point: Not-Associated
          Bit Rate:0 kb/s   Tx-Power:16 dBm
          Retry limit:15   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:1413   Missed beacon:0


Instalei o driver da intel 3945 e o wpa_supplicant usando o emerge. No meu AP está configurado WPA-PSK.
Será que alguém tem uma dica sobre o que pode estar acontecendo? Como posso solucionar esse problema?

Peço desculpas por recorrer tão rapidamente a este forum. Pois estive olhando um wiki do Gentoo (http://gentoo-wiki.com/HOWTO_Wireless_Configuration_and_Startup) sobre a configuração de placa wi-fi, quando lembrei que coloquei o suporte aos protocolos de segurança TKIP, WEP e CCMP como módulos no kernel. Portanto foi só incluí-los no arquivo /etc/modules.autoload.d/kernel-2.6 que consegui autenticar com meu AP.

O Arquivo /etc/modules.autoload.d/kernel-2.6 ficou assim:
Code:

sha256
cbc
pcbc
sha1
ieee80211_crypt_tkip
ieee80211_crypt_ccmp
ieee80211_crypt_wep
scsi_wait_scan
lcd
output
backlight
padlock-aes
geode-aes
padlock-sha
ipw3945
