iwl4965 not work on intrepid 2.6.27-7 (64 bit)

[techmin]

In intrepid 64 bit with kernel 2.6.27-7 the wireless don't work:

[ 2883.718180] wlan0: associated
[ 2883.739229] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready
[ 2883.739336] wlan0: disassociating by local choice (reason=3)
[ 2885.736401] wlan0: privacy configuration mismatch and mixed-cell disabled - disassociate

I have the firmware.

Why iwl4965 is built-in in the kernel?
I like to manually compile the compile compat-wireless-2008-11-24 but with iwl4965 built-in is not possible to use.

Hi techmin,

Is this still an issue with the more recent 2.6.27-9.19 kernel? If so, can you try installing the linux-backports-modules-intrepid package as it contains and updated compat-wireless stack? Please let us know your results. Thanks.

Installed the backport but not work, this is the backtrace:

Other info

 wlan0: disassociating by local choice (reason=3)
 wlan0: privacy configuration mismatch and mixed-cell disabled - disassociate

Is present with backport kernel to

Note with ubuntu 8.04 wireless work fine.

Care to do one more test. In the intrepid-proposed repository there is an newer linux-backports-modules-intrepid package that has a newer update of the compat-wireless stack ( https://launchpad.net/ubuntu/+source/linux-backports-modules-2.6.27 ). To test the package in intrepid-proposed do the following:

1) cd /etc/apt/sources.list.d
2) create a file "intrepid-proposed.list" which contains the following two lines (sudo vim intrepid-proposed.list):

deb http://archive.ubuntu.com/ubuntu/ intrepid-proposed main
deb-src http://archive.ubuntu.com/ubuntu/ intrepid-proposed main

3) sudo apt-get update
4) sudo apt-get install linux-backports-modules-intrepid
5) sudo rm /etc/apt/sources.list.d/intrepid-proposed.list
6) sudo apt-get update

Steps 5 and 6 basically undo the enabling of intrepid-proposed. Of course you'll finally need to reboot to test. Please let us know your results. If this issue still exists we'll want to work on reporting this to the upstream developers.

Additionally, I think you should also be able to manually compile and test the latest upstream development compat-wireless stack http://linuxwireless.org/en/users/Download since you're using the iwlagn driver. It would be great if you'd be willing to give this a test a well as I'm sure the upstream developers would appreciate feedback from the current development stack. Thanks.

Same problem with proposed kernel
I suppose the problem is in disasocciating:

Hi techmin,

Thanks again for all the testing. You mentioned "I have compiled and installed compat-wireless-2008-12-11
but i have same problem (but the scan work)". Care to reproduce the issue again with compat-wireless-2008-12-11 installed and capture the corresponding log information. Can you then send that information in an email to the linux-wireless mailing list so that the upstream developers are notified:

http://linuxwireless.org/en/developers/MailingLists#Statsandrequirementsoflinux-wirelessmailinglist

Thanks.

[techmin (info-techemia)]

Ok sended info on linuxwireless mailing list

[techmin (info-techemia)]

Found the problem (with the help of linux wireless mailing list).
I am very sorry for disturb.
The problem is that:
Ubuntu have startup script network-manager
i disabled graphical network manager, but i didn't know that ubuntu has a startup network-manager script (and wpa supplicant script). I have killed process related to network-manager and wireless work correctly.

I am sorry for the time you have spent for my problem.
Tank you very much to all (and to linux wireless mailing list).

P.S. i suppose this bug need to be closed

[Leann Ogasawara (leannogasawara)]

Thanks for the update. I'll go ahead and close this one out.
