Hi,
Not so long time ago there was a thread about networkmanager and
ipw3945. I
had similar problem and therefore I decide to write.
I have router with wpa psk. When I us wpa_supplicant it connects
and I can
without any problem use network. When I use networkmanager (with
knetworkmanager applet) it keeps asking for the passphrase all the
time (only
in few cases it managed to connect to the network). I searched for
the reason
and below is what I discovered.
I was monitoring wpa_supplicant using wpa_cli. I have found, that
when it
connects to my network, it first get disconets, then get timeout
from
00:00:00:00:00:00 (whatever it is), and then it tries the second
time with my
network and this time it connects to the ap. The log from wpa_cli
below:
2Trying to associate with 00:18:4d:b9:be:44
(SSID='ilonka_i_piotrek' freq=0
MHz)
2CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
2Authentication with 00:00:00:00:00:00 timed out.
2Trying to associate with 00:18:4d:b9:be:44
(SSID='ilonka_i_piotrek' freq=0
MHz)
2Associated with 00:18:4d:b9:be:44
2WPA: Key negotiation completed with 00:18:4d:b9:be:44 [PTK=TKIP
GTK=TKIP]
2CTRL-EVENT-CONNECTED - Connection to 00:18:4d:b9:be:44
completed (auth)
Above is when I connect using directly wpa_supplicant. But when I
use
networkmanager the situation looks similar, but the question for
passphrase
appear all the time. When I monitored what is going on with
wpa_supplicant
called by networkmanager using wpa_cli I got below log:
2Trying to associate with 00:18:4d:b9:be:44
(SSID='ilonka_i_piotrek' freq=0
MHz)
2CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
At this point the networkmanager thinks that there was some
problem with
password and asks for the password again. When I write it once
again, the
situation repeats. But when I do not write password and observe
wpa_supplicant, it connects to the ap after some time, the same
like in case
of direct use of wpa_supplicant:
2Authentication with 00:00:00:00:00:00 timed out.
2Trying to associate with 00:18:4d:b9:be:44
(SSID='ilonka_i_piotrek' freq=0
MHz)
2Associated with 00:18:4d:b9:be:44
2WPA: Key negotiation completed with 00:18:4d:b9:be:44 [PTK=TKIP
GTK=TKIP]
2CTRL-EVENT-CONNECTED - Connection to 00:18:4d:b9:be:44
completed (auth)
Of course nm does not know anything about that because it keeps
asking for the
new pasphrase.
It seems, that in every case when wpa_supplicant connects to my ap
it first
time get CTRL-EVENT-DISCONECTED, and then finally repeats
connection and
connects. But nm does not know that and thinks that there was
something wrong
with passphrase.
Is there any solution of this problem. Because of that I am not
able to use
nm. The system is fc6 with some rawhide updates. The packages
versions below:
wpa_supplicant-0.4.9-1.fc7
NetworkManager-0.6.5-0.3.cvs20061025.fc7
kernel-2.6.19-1.2911.6.5.fc6
