iwl3945: cannot connect to hidden wpa-psk network

Actually, if I look in /var/log/syslog, the kernel error code in the the AssocResp is a bit different (18 instead of 128):

Aug 20 11:02:34 platonas kernel: [ 33.381224] eth1: Initial auth_alg=0
Aug 20 11:02:34 platonas kernel: [ 33.381235] eth1: authenticate with AP XX:XX:XX:XX:XX:XX

Google tells me 802.11 status code 18 means "association denied; the mobile station does not support all of the data rates required by the BSS"

Hi Marius,

Care to test a few things . . . First can you try installing the linux-backports-modules package as I believe it has an updated version of the iwl4965 driver - you can check the output of 'modinfo iwl4965' to see which version you have. Along with that you might want to wait for the linux-backports-modules that is in the -proposed repository to be released as it looks to by sync'd with the upstream compat-wireless stack:

https://edge.launchpad.net/ubuntu/+source/linux-backports-modules-2.6.24

Additionally, since the upcoming Intrepid Ibex 8.10 release is actively being developed, care to confirm if this is still an issue with the latest Alpha for the upcoming Intrepid Ibex 8.10. You should be able to test via a LiveCD - http://www.ubuntu.com/testing. Please let us know your results. If the issue still exists, per the kernel team's bug policy, can you please attach the following information. Please be sure to attach each file as a separate attachment.

* cat /proc/version_signature > version.log
* dmesg > dmesg.log
* sudo lspci -vvnn > lspci-vvnn.log

For more information regarding the kernel team bug policy, please refer to https://wiki.ubuntu.com/KernelTeamBugPolicies . Thanks again and we appreciate your help and feedback.

And finally, just some info that beginning with the Intrepid Ibex 8.10 development cycle the linux-ubuntu-modules package was actually merged with the linux kernel package. Going forward, bugs that would have been reported against linux-ubuntu-modules should now just be reported against linux. I've gone ahead and opened the 'linux' task for this bug so that it remains open against the actively developed kernel. Thanks.

Thank you for mentioning linux-backports-modules. Installing it fixed my wireless problem.

Summary:
* iwl3945 version 1.2.0 from linux-ubuntu-modules-2.6.24-21-generic version 2.6.24-21.30 fails to connect.
* iwl3945 version 1.2.26k from linux-backports-modules-2.6.24-21-generic version 2.6.24-21.25 works fine.

Thanks Marius,

I'm going to mark this Fix Released against the linux-backports-modules package.

A warning for people who have this problem and find this bug report: iwl3945 from linux-backports-modules 2.6.24-21.25 makes the kernel panic on suspend (bug 251252). You have to choose between working wifi (install linux-backports-modules, or working suspend (uninstall linux-backports-modules).

Why is this bug invalid? This is a bug in the current hardy kernels (all of them)

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.
