once again wpa_supplicant problem:

ezzetabi · 2009-09-30 21:30:39

I'd like to `upgrade' my wireless connection from the not-so-good wep to the shining wpa2, but I continue having problems...

Some general informations, I think everything is fine:

# lspci | grep lan
02:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
# rmmod iwl3945
# modprobe iwl3945
# cat wpa_supplicant.conf
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel

network={
    ssid="rimururu"
    proto=RSN WPA
    #psk="not so secret"
    psk=9481d66541c04cb6c00870ad872d0c233fb05bac609eb4674be0fff6e17b8f30
}

Yet, when I try to associate... it does not work:

The `ioctl[SIOCSIWENCODEEXT]: No such file or directory' sounds fairly suspicious, but I have no idea (nor google I'd say) of the meaning.

Any idea? Thanks for any insight.

Why don't you try with WPA1 first?

ezzetabi · 2009-10-01 07:32:15

I seems working with wpa1... Are there many disadvantages? (Thanks btw)

arkham · 2009-10-01 08:52:47

Well, some time ago it was discovered a potential vulnerability in WPA-TKIP, but it is still much safer than WEP

ezzetabi · 2009-10-01 09:38:31

and maybe it is not such much of a problem as I use wpa ccmp...

parintachin · 2009-10-02 01:17:31

try this
network{
ssid="youressid"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
psk="your secret in plain text"
#or psk=your secret as hex
}

wpa_supplicant has big problems with wpa2-psk
already described in ubuntuforum as well
I had to switch to wep for this reason :-(

Thanks, but before coming here I tried all combinations... CCMP, TKIP... Even set group=CCMP. It seems having not effect

this is rather strange because i have no problem with wpa2 and wpasupplicant (using autowifi for wireless).
have tried looking with wpa_cli where the problem is ?

ps. are you sure tht your router is using wpa2 ccmp and not wpa2 tkip?

sorry for doublepost hit quote instead of edit
