Description Chris Murphy 2014-08-06 00:03:27 UTC
Description of problem: Sometimes Wifi connects at boot time, and when it does it remains connected reliably. Perhaps 50% of the time, it fails to connect at boot time for reasons I don't understand, and no wifi networks are seen at all. No applicable kernel messages. Version-Release number of selected component (if applicable): NetworkManager-0.9.10.0-2.git20140704.fc21 kernel-3.16.0-1.fc21.x86_64 kernel: b43-phy0: Loading firmware version 666.2 (2011-02-23 01:15:07) How reproducible: Non-determinstic. It *seems* like cold boots are more reliable than warm boots. Steps to Reproduce: 1. Boot. Actual results: No wifi networks visible at all in gnome networkmanager UI. I think this is the bottom line problem "(wlp3s0): not available because supplicant interface not ready" I just don't know the cause since there are no kernel messages. Expected results: Consistent connections every boot.

Comment 5 Chris Murphy 2014-08-06 00:09:12 UTC
Created attachment 924306 [details] nwmdebug.txt Enabled level=DEBUG in NetworkManager.conf, restarted NetworkManager, used the GUI to turn off the WiFi radio, started a journalctl -f -u NetworkManager capture, and then turned the WiFi back on and waited for about a minute. Result attached. Even after turning it off then on, I still get the same results. So far 100% of the time *if* at boot time wireless isn't working, I can't make it work post-boot. If it works at boot time, I can't make it fail. So it seems like it might be a kernel problem, yet I'm not getting any kernel messages which I'd sorta expect if there are kernel-hardware related problems. *shrug*
Comment 6 Chris Murphy 2014-08-06 00:36:31 UTC
This might be a manifestation of bug 1061836, despite no kernel messages. I'm not sure if that bug shows messages only with debug kernels.

Comment 8 Chris Murphy 2014-08-07 19:56:11 UTC
Created attachment 925015 [details] journal (full) with debug NetworkManager set to debug, as well as wpa_supplicant. This journal goes with the previously attached wpa_supplicant.log. So far all cold boots have working wifi, while most warm boots don't. Once the problem starts, it's looking like it needs a shutdown to resolve the problem.
Comment 9 Jirka Klimes 2014-08-19 12:50:30 UTC
Any better with newest kernel and wpa_supplicant? Did you try with another card (a USB Wi-Fi dongle)? Please check whether the Wi-Fi is not blocked: $ rfkill list # rfkill unblock all $ nmcli general $ nmcli radio wifi on
Comment 10 Chris Murphy 2014-08-22 02:01:54 UTC
kernel-3.16.0-1.fc21.x86_64 wpa_supplicant-2.0-9.fc21.x86_64 NetworkManager-0.9.10.0-3.git20140704.fc21.x86_64 Same kernel as before but I think newer wpa_supplicant (? not sure since I didn't previously report its version), and newer NetworkManager. I've only tried a few times so far, but warm reboots do have working wireless with this combination; previously it was completely consistent that I'd have to power off and cold boot to resolve the problem. So it's looking better so far.
Comment 11 Chris Murphy 2014-08-24 04:07:15 UTC
OK it happened again on a warm boot. # rfkill list 0: hci0: Bluetooth Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no # rfkill unblock all # nmcli general STATE CONNECTIVITY WIFI-HW WIFI WWAN-HW WWAN connected (local only) limited enabled enabled enabled enabled # nmcli radio wifi on No change. I have to cold boot to resolve it.

Comment 13 Fedora End Of Life 2015-11-04 10:48:58 UTC
This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '21'. 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 21 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.
Comment 14 Fedora End Of Life 2015-12-02 03:21:09 UTC
Fedora 21 changed to end-of-life (EOL) status on 2015-12-01. Fedora 21 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.
