If more info is needed, please let me know how to obtain the info and I will try to provide it.
Comment 2 Emmanuel Grumbach 2015-02-03 15:40:11 UTC
do  you have several instances of the supplicant running?

the driver seems healthy here..
Comment 3 mwp.junk 2015-02-03 16:14:52 UTC
No, there is only one wpa_supplicant running:

root      1024  0.2  0.0  51220  6712 ?        Ss   09:09   0:00 /usr/sbin/wpa_supplicant -u -f /var/log/wpa_supplicant.log -c /etc/wpa_supplicant/wpa_supplicant.conf -u -f /var/log/wpa_supplicant.log -P /var/run/wpa_supplicant.pid

Is there some other log I can provide?

Weird.
Still not working?

Can you try this:

sudo rfkill unblock 0

Does not seem to matter... the wireless continues to soft block endlessly.
Comment 9 Emmanuel Grumbach 2015-02-03 20:55:21 UTC
ok - this is not a wifi driver issue for sure.
Please contact your distribution.
Comment 10 mwp.junk 2015-02-03 21:29:39 UTC
Not to be rude, but care to explain why it's specifically a distribution issue in case they tell me it's a kernel issue? ;-)
Comment 11 mwp.junk 2015-02-03 21:32:58 UTC
Fedora bugzilla I created: https://bugzilla.redhat.com/show_bug.cgi?id=1188867
Comment 12 Emmanuel Grumbach 2015-02-03 21:41:00 UTC
:)

Because if there was a bug in the driver and we would wrongly report that the device is in RFKill, then it would be Hardware and not Software Blocked.

Also - I didn't see anything in your logs. When the NIC issues an RFKill interrupt (Hardware) it prints something in the logs (regardless of the logs level). So basically, you have a small bastard somewhere which is constantly playing with the Software kill state and that can't come from the WiFi driver.

It can be a *kernel* issue in a way that WMI driver or any platform specific thing like special buttons or whatever. But that's not related to the WiFi driver on which this bug was routed.
In that case, I'd expect the distro to help you out with finding what it could be.

HTH
Comment 13 Emmanuel Grumbach 2015-02-04 16:49:04 UTC
Not related to Intel WiFi. Removing them.
Comment 14 mwp.junk 2015-02-04 22:13:26 UTC
I tried Ubuntu 14.10 liveCD and the same issue can be seen with one exception: the acer-wireless interface stays soft blocked instead of bouncing back and forth. If I attempt to unblock it with rfkill, it immediately reblocks.
Comment 15 mwp.junk 2015-02-17 22:13:41 UTC
Has anyone looked at this? Any new info?
Comment 16 mwp.junk 2015-03-10 22:40:30 UTC
Same issue with F22 alpha which uses kernel 4.0 RC2
Comment 17 mwp.junk 2015-08-03 16:52:10 UTC
This issue use to be an acer-wmi problem (workaround, rmmod or blacklist acer-wmi); however, with 4.0.4 kernel the iwlwifi firmware is hard blocking the wifi card.

I now see the following in dmesg output:

RF_KILL bit toggled to disable radio

and rfkill shows:

0: hci0: Bluetooth
        Soft Blocked: yes
        Hard Blocked: no
1: phy0: Wireless LAN
        Soft Blocked: no
        Hard Blocked: yes
Comment 18 Emmanuel Grumbach 2015-11-22 07:28:43 UTC
still a problem?

Please share the output of ethtool -i wlan0.
