dmesg

Description of problem:
When running 2.6.38, I can connect to my wireless router without any problems. On 2.6.40, however, wireless access points are visible, but it fails to connect. The network in question is wireless-G. The system is fully updated.

Version-Release number of selected component (if applicable): 2.6.40


How reproducible:
Always

Steps to Reproduce:
1. Connect to the desired AP from the network applet
2. Wait for it to connect
3. A connection is successfully established

Actual results:
Unable to connect, after which it will bring up the WPA2 key dialog, even though the stored key is correct

Expected results:
A connection should successfully be established.

Additional info:
This seems to affect Ubuntu 11.10 as well.

Only happen for WPA2? how about "Open"

Wey

Comment 4 Lawrence Patrick Calulo 2011-10-20 11:19:57 UTC
After disabling wireless security on my router, I am still unable to connect. dmesg output is identical.

Comment 5 John W. Linville 2011-11-07 19:31:56 UTC
Can we see the contents of /var/log/messages after a connection failure?

Here's a connection attempt to a WPA2 router at a local coffee shop.

Nov  8 11:17:58 derpbook kernel: [   31.103992] iwlagn 0000:03:00.0: fail to flush all tx fifo queues

Some sort of Tx queue hang?

Comment 8 Josh Boyer 2012-06-07 14:58:08 UTC
Is this still happening with 2.6.43/3.3?

Comment 9 Lawrence Patrick Calulo 2012-06-08 03:29:09 UTC
I no longer own the laptop that I experienced this issue on, and I don't have access to an identical wireless card.
