wpa_supplicant Connects, then Hangs

English Network/Internet
1

Hello,

after issuing “wpa_supplicant -i wlan0 -D wext /etc/wpa_supplicant/wpa_supplicant.conf” in command mode, wpa_supplicant hangs; last echo is
“CTRL-EVENT-CONNECTED - Connection to <router address> completed (auth) [id=0 id_str=]”.

Tho mention is that I run opensuse 11.3, and that at W_S startup, I see the message
“ioct[SIO_CSIWENCODEEXT]: Invalid argument” two times.

Any idea?

Best regards,
J C Anker****

What wireless device

Hello caf4926,

the device is Atheros AR928X.

Are you telling us that you only have issues with WPA
or is there issues even without security?

HCL:Network (Wireless) - openSUSE

Hello caf4926,

I believe that the issues are with WPA, since the device connects. However, I do not see the significance of the “ioct[SIO_CSIWENCODEEXT]: Invalid argument”
message, as my wpa_supplicant.conf-file is pretty standard:
ctrl_interface=/var/run/epa_supplicant
ctrl_interface_group=0
network={
ssid=
pairwise=TKIP
group=TKIP
key_mgmt=WPA-PSK
psk=
proto=WPA
}

Thanks for your efforts so far!
J C Anker

Are you then telling us that it connects correctly with no security?
Just so we are clear on this

Sorry, I was unclear, the ssid and psk are set, it is connecting WITH security!

Hello caf4926,

I have issued a bug-report at bugzilla (#397).

Thanks for your efforts and best regards,

Is there a particular reason that you are using ifup rather than NetworkManager?

With recent versions of wpa_supplicant, NetworkManager, and kernel drivers, the
D-bus interface to the supplicant is employed. That might make a difference.

Interesting.

Search for “wpa_supplicant” on bugzilla.novell.com

Where?

Reason(s):

Need a connection to get NetworkManager working. Need a connection to get zypper working. Almost have a connection with wpa_supplicant (ref previous posts).
As far as I know, I am not trying using ifup.

Best regards,

Hello pistazienfresser,

see Bug 397 – wpa_supplicant Connects, then Hangs / opensuse 11.3 (nothing new there, simply a reference to this thread).

Hi J C,

thanks for the link. I thought there where a half of the digits missing in the number…:shame:

But as you have written is really Bug #397 - on the bugzilla of Jouni Malinen, the (main) developer of wpa_supplicant / on the wpa_supplicant bugzilla / ‘upstream’.
I am not very experienced nor have I ever been something even close to a software developer but I would doubt that it is a good idea to give in the report nearly not any data - the developer would even have to visit this forum to know that version of software / distribution you are using…:wink:

I am here really in the area of guessing around but maybe something like explained in the (a bit old?) wiki article SDB:Tracking down wireless problems - openSUSE under the paragraph wpa_supplicant would be able to produce a bit more data?

Hello pistazienfresser (Martin),

two things:

I did not want to bombard JM with a massive amount of data, I asked him for exactly what he needed (I have been developing software and would prefer to inquire for nothing more and nothing less than I need).

The article you are referring to I have read more than 10 times (without missing too much, I suppose). The problem is that wpa_supplicant establishes the connection and then hangs (ctrl-break after some 45 minutes on one occation). googling wpa_supplicant indicates that there are problems “now and then”.

Best regards,
J C Anker (Jan Christian)

Thanks Jan Chistian

NetworkManager makes the connection, and it does not use the outdated wext
interface to wpa_supplicant. I don’t know if that is the reason for the hang,
but it looks suspicious.

Hello Martin,

I am giving up on finding a solution to my problems. Let me clearly express that this is not due to lacking help from the forum, the attempts from everyone to find a solution are greately appreciated. At the moment, I am backing up the whole computer to be able to reinstall openSuSE “without too much fear”.

Summing up / drawing conclusions:

  1. I think some essential files have been lost during an unsuccesful attempt on installing the gcc FORTRAN compiler.
  2. wpa_supplicant seems to be a candidate for improvements.
  3. Yast needs to have access to the net to recover lost system files.
  4. NetworkManager can not be run in command mode.
  5. I have learnt a lot about linux during the exercise.
  6. I should have opted for a reinstall of the system as soon as the problems materialized (from the CD).
  7. This forum is great!

Thanks and best regards,
Jan Christian
