Description Christophe Dumez 2008-09-20 00:51:50 UTC
Latest working kernel version: Linux-2.6git (~linux-2.6.27-rc6)
Earliest failing kernel version: unknown
Distribution: Vanilla
Hardware Environment: Intel 4965agn card
Software Environment:
Problem Description: Although my wifi card is detected, and although it is able to scan for access points, it is not able to connect to access points. I tried two access points (one with WPA2 encryption and another without encryption).
Authentication is successful but then it seems like it is not able to get an IP from DHCP... DHCP server is working fine and forcing an IP does not work (I'm not able to ping other machines on the wlan).

I first noticed this problem on Ubuntu intrepid, which is using 2.6.27-rc6. Then, I decided to compile linux-2.6 git and enable iwlagn debug.

I'm joining my logs. I'll be happy to provide more information if necessary.

Steps to reproduce: Connect to any access point, authentication is successful but you can't get any IP.

hm, so we broke it in the past few days?
Comment 7 Christophe Dumez 2008-09-20 01:07:36 UTC
I'm not exactly sure when it was broken. I switched directly from
kernel 2.6.26 (which was working fine) to kernel 2.6 git
(~2.6.27~rc6).

Comment 8 Christophe Dumez 2008-09-20 01:15:11 UTC
I don't think it was broken that recently though. I experienced the
same problem with ubuntu kernel :
2.6.27-2.3

Which apparently was based on git and was released on :
Wed, 27 Aug 2008 14:03:05 -0400

Best regards,
Chris.

Comment 9 Zhu Yi 2008-09-21 19:31:59 UTC
The same bug is also reported here:
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1761
Comment 10 Jan Vcelak 2008-10-11 06:24:05 UTC
The same problem here. In vanilla 2.6.26.6 it is working, in 2.6.27 it does not.

Kismet shows wireless networks around, therefore the monitoring mode is probably working correctly. But scanning with iwlist returns: Operation is not supported. Manual connection to AP is not possible.
Comment 11 Zhu Yi 2008-10-12 19:45:46 UTC
Did you also enable 40MHz FAT channel?

Yes, I do.

(In reply to comment #12)

Correction: Yes, I did. (sorry; to prelude misunderstanding)
Comment 14 Jan Vcelak 2008-11-01 10:26:48 UTC
I upgraded kernel to version 2.6.27.4 and don't have this problem any more.
