Summary: connecting to secure wireless network fails most of the time. Classification: openSUSE Product: openSUSE 11.3 Version: Milestone 6 Platform: Other OS/Version: Other Status: NEW Severity: Major Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: bwhiteley@novell.com QAContact: qa@suse.de Found By: Development Blocker: ---

Created an attachment (id=358310) --> (http://bugzilla.novell.com/attachment.cgi?id=358310) /var/log/NetworkManager

Most of the time, connecting to a secure wireless network with NetworkManager fails. Occasionally it works, after several tries. Sometimes countless attempts will yield no success. If I reboot back into 11.2, I can connect immediately.

Please share a workaround if you come up with one. This is a really painful bug.

You can try to setup traditional ifup/ifdown method in Yast network settings. If you can connect this way then I can help you setup wpa_gui [1].

I'm guessing that my driver (iwl3945) is not supported by wpa_supplicant.

I can connect to my home lan (WPA2-personal) with NM. I can't connect to a work lan (WPA2-enterprise) with either NM or traditional mode.

Yes, There is a problem with WPA-EAP and the Intel driver(s) in 2.6.33 .

Fresh MS5 installation [1] in runlevel 3 (some X problems in T60) with Intel 3945 [2]. NM is off [3] and wpa_supplicant configured to connect to the WPA-EAP network. From the wpa_supplicant.conf can be seen that the full EAP authentication did not pass. The same happens most of the time with Intel 5100 [5] and iwlagn driver too, but occasionally the iwlagn connects [6]. The full wpa_supplicant.log is attached to the next comment. Unfortunately, no time to investigate further.

Thank you. This is still work in progress. I suggest to wait until it is ready.

--- Comment #13 from Andreas Jaeger aj@novell.com 2010-05-27 19:12:10 UTC --- I don't understand why this should be kernel related. I run the 11.3 kernel on 11.2 without problems. The firmware is in both environments the same (same md5sum). So, to me it looks like either a compiler issue or a userland issue - but not firmware or kernel in general.

this does not seem to be like the Red Hat bug a issue with heavy load - the system is idle in my case.

I have enabled debug on iwl3945 and tried to connect WPA-EAP "Novel" network. Packets were sniffed from the air.

I was not able to connect either with NM on channel 44 or on channel 11 with ifup/ifdown. In both cases the iwl3945 driver repeatedly "deauthenticated" with "Unspecified reason"reason=1 .

On channel 44 the AP responded to the "probe request" but the STA did not try to associate. On channel 11 there was no response from the Novell AP to the "probe request" !

This is all I can tell for sure now. To investigate these kind of problems is rather time consuming. I will have to setup WPA-EAP authentication backend on my own and try to reproduce with the WPA-EAP under control.

Just few more notes for the record

(a) "iw list" shows that only passive scanning is allowed on channel 44

5220 MHz [44] (14.0 dBm) (passive scanning, no IBSS)

(b) https://patchwork.kernel.org/patch/96097/ states:

Some firmware versions don't behave properly when passive scanning is requested on radar channels without enabling active scanning on receiving a good frame. Work around that issue by asking the firmware to only enable the active scanning after receiving a huge number of good frames, a number that can never be reached during our dwell time.

Would it be possible to try the wpa_supplicant from the "hardware" project ?
