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.

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).

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.

The same bug is also reported here: http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1761
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.
Did you also enable 40MHz FAT channel?

(In reply to comment #12) > Yes, I do. Correction: Yes, I did. (sorry; to prelude misunderstanding)
I upgraded kernel to version 2.6.27.4 and don't have this problem any more.
