Created attachment 823873 [details] Dmesg output for attempted connection Description of problem: WiFi stopped connecting to the wifi router at my work place -- story short, I was out of office delivering training for a few days, before training it worked ok (wifi dropped once every few hours, usual), now it does not connect at all. There was a firmware update, but sysadmin is unable to tell me what was updated - he said, nothing has changed, just a firmware update to the latest version. My Android phone still connects to the same wifi with no issues (password has not changed). From dmesg, it seems to connect then it's de-authenticating for reason 3: deauthenticating from 00:19:77:8a:f8:29 by local choice (reason=3) Hardware: Dell XPS 13 Developer's edition Network controller: Intel Corporation Centrino Advanced-N 6235 (rev 24) Version-Release number of selected component (if applicable): # rpm -qa | grep NetworkManager NetworkManager-pptp-gnome-0.9.8.2-3.fc19.x86_64 NetworkManager-pptp-0.9.8.2-3.fc19.x86_64 NetworkManager-openvpn-0.9.8.2-3.fc19.x86_64 NetworkManager-vpnc-gnome-0.9.8.2-2.fc19.x86_64 NetworkManager-glib-0.9.8.8-1.fc19.x86_64 NetworkManager-0.9.8.8-1.fc19.x86_64 NetworkManager-openconnect-0.9.7.0-2.git20120918.fc19.x86_64 NetworkManager-openvpn-gnome-0.9.8.2-3.fc19.x86_64 NetworkManager-l2tp-0.9.8-4.fc19.x86_64 NetworkManager-vpnc-0.9.8.2-2.fc19.x86_64 # uname -a Linux warbird 3.11.7-200.fc19.x86_64 #1 SMP Mon Nov 4 14:09:03 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux How reproducible: Since today's morning, every time (tried rebooting, tried removing and adding wifi connection again). Steps to Reproduce: 1. Connect to the wifi network Actual results: Not connected Expected results: Connected Additional info: See attached log for dmesg output.
Additional info from the admin: I just saw it pop up. As you can see it is failing at part 1 of 4: 11/14/2013 02:53:55 PM B4B6762AF36E 0019778AF954 aerohive01.ibuildings.uk BASIC (40)Rx auth <open> (frame 1, rssi 37dB) 11/14/2013 02:53:55 PM B4B6762AF36E 0019778AF954 aerohive01.ibuildings.uk BASIC (41)Tx auth <open> (frame 2, status 0, pwr 14dBm) 11/14/2013 02:53:55 PM B4B6762AF36E 0019778AF954 aerohive01.ibuildings.uk BASIC (42)Rx assoc req (rssi 45dB) 11/14/2013 02:53:55 PM B4B6762AF36E 0019778AF954 aerohive01.ibuildings.uk BASIC (43)Tx assoc resp <accept> (status 0, pwr 14dBm) 11/14/2013 02:53:55 PM B4B6762AF36E 0019778AF954 aerohive01.ibuildings.uk INFO (44)WPA-PSK auth is starting (at if=wifi0.1) 11/14/2013 02:53:55 PM B4B6762AF36E 0019778AF954 aerohive01.ibuildings.uk INFO (45)Sending 1/4 msg of 4-Way Handshake (at if=wifi0.1) 11/14/2013 02:53:59 PM B4B6762AF36E 0019778AF954 aerohive01.ibuildings.uk INFO (46)Sending 1/4 msg of 4-Way Handshake (at if=wifi0.1) 11/14/2013 02:54:03 PM B4B6762AF36E 0019778AF954 aerohive01.ibuildings.uk INFO (47)Sending 1/4 msg of 4-Way Handshake (at if=wifi0.1) 11/14/2013 02:54:07 PM B4B6762AF36E 0019778AF954 aerohive01.ibuildings.uk BASIC (48)Sta(at if=wifi0.1) is de-authenticated because of 4way handshake failure 11/14/2013 02:54:07 PM B4B6762AF36E 0019778AF954 aerohive01.ibuildings.uk BASIC (50)Sta(at if=wifi0.1) is de-authenticated because of notification of driver This usually indicates that the packet the device is sending to the AP isn’t being fully received.

This message is a notice that Fedora 19 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 19. It is Fedora's policy to close all bug reports from releases that are no longer maintained. Approximately 4 (four) weeks from now this bug will be closed as EOL if it remains open with a Fedora 'version' of '19'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 19 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
I am bumping this ticket because I had a similar problem and I found out that code 3 means "The access point went offline, deauthenticating the client." http://www.aboutcher.co.uk/2012/07/linux-wifi-deauthenticated-reason-codes/
