hi there,

i have a problem with my connection to my local router. i emerged wpa_supplicant and switch the router to wpa. i had a connction at first, switch back to WEP for a sec just to modify something on the router. switched back to wpa and nothing works anymore. a windows machine has a wonderful connection with wpa to that router. my problem is that i do not get information from the output to solve this problem. i will try to give you all the info i can get and maybe someone can help me.

my /etc/wpa_supplicant/wpa_supplicant.conf:
Code:
network={
        ssid="homenet"
        scan_ssid=1
        key_mgmt=WPA-PSK IEEE8021X NONE
        auth_alg=OPEN SHARED
        pairwise=CCMP TKIP
        group=CCMP TKIP WEP104 WEP40
        psk="keyword"
        eap=TTLS PEAP TLS
}


my /etc/conf.d/net:
Code:
modules=( "wpa_supplicant" )
wpa_supplicant_eth1="-dd -Dwext"
wpa_timeout_eth1=10
config_eth1=("dhcp")
dhcpcd_eth1="-t 10 -R -N"


and the console output:

Have you tried one of the simpler examples from /usr/share/doc/wpa_supplicant-0.5.4/wpa_supplicant.conf.example.gz: for example
Code:
# Simple case: WPA-PSK, PSK as an ASCII passphrase, allow all valid ciphers
network={
        ssid="simple"
        psk="very secret passphrase"
}
or
Code:
# Same as previous, but request SSID-specific scanning (for APs that reject
# broadcast SSID)
network={
        ssid="second ssid"
        scan_ssid=1
        psk="very secret passphrase"
}
It seems to be getting into trouble with EAPOL, perhaps something simpler will work.

What does wpa_cli show while it's trying to connect? Do the logs on your wireless AP show actual connection attempts? What hardware are you using? Have you tried killing all the wpa_supplicant processes, rmmoding the wireless card modules, and then modprobing and restarting wpa_supplicant?

for some reason the simpler config wynn suggested worked out well, although the output concerning EAPOL remained the same. strange.

Myh understanding is that EAPOL has to be disabled until after the encryption has been negotiated correctly. So when connecting to an encrypted wifi network, wpa_supplicant will temporarily disable EAPOL and then re-enable it following negotiation of the encryption.

Glad you got it working. =)
