[fedora-arm] wlan0 de-activated?

[Robert Brown]

Hi all
Running Fedora release 22 (Rawhide) 3.19.0-0.rc7.git3.1.fc22.armv7hl I 
find I have a problem with wlan0 becoming de-activated.
Running headless, attempt to ssh to device. No response. Turn on monitor 
at device.
ifconfig shows an ip address ok.
cannot ping router
try |sudo systemctl restart network.service|
no change
decide to ifdown/ifup wlan0
system returns to normal, can then ping router and ssh to device from my 
laptop.
journalctl for wlan0 gives results as per attached.
Can anyone explain what is happening to the wlan0 device and why I have 
to re-activate it?

Thanks
Rob
