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
sudo systemctl restart network.service
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?
