8086:4237 NM disconnects from 802.1x network shortly after authenticating -- Intel PRO/Wireless 5100 iwlwifi

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.5kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the other tags). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Joseph,

Tested against 3.5.0-030500rc7 my wifi fails to connect to 802.1x at all--so if anything its a regression.

The kernel fails to probe for the network, so it's unlikely that this has anything to do with issues in NetworkManager. Could you please provide debug logs for wpasupplicant?

You can get those by running:

sudo python /usr/lib/NetworkManager/debug-helper.py --wpa debug

Before reproducing the connection attempt. Logs will be in /var/log/syslog; which you can then attach to this bug report.

Thanks!

Mathieu --

My first attachment contains a wpasupplicant debug log created with "debug-helper.py --wpa msgdump" turned on. (-nm debug too)

(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1024740/+attachment/3223273/+files/syslog.txt)

If running it with debug will provide more useful information than msgdump let me know and I'll run it again.

Cheers.

I'm setting statuses back to confirmed in lieu of someone telling me I need to run the logs again (see previous comment).

Patrick Kilgore, thank you for reporting this and helping make Ubuntu better. Did this problem occur in prior versions of Ubuntu?

I do not know, I did not need to use this network earlier.

Or - let me be more precise, this type of network.

Patrick Kilgore:
+ What is the manufacturer and model of the router you are connecting to?

Its an enterprise setup, at a university so i have no router information.

I have no CDROM drive on the laptop, so testing with a live cd will be
difficult, it their any other way to test against lucid.

If you could please ask your university IT department for the requested information it would be really great to have.
