Jul 14 17:02:21 arch systemd[1]: Started Cleanup of Temporary Directories.One line mentions netctl-auto@wlp16s0 including the appropriate wireless access, but then dhcpcd tries to connect wired service.
Is rfkill killing iwl4965, which is required?
Does terminationg wpa_actiond session stop the connection process? If so, what is making it terminate?
Sometimes on booting the connection is established but usually not (it always connected until recently). Debian wheezy which is in another partition on the same computer always connects.
Help appreciated.

Re: Wifi connection not found
Is your interface always called "wlp16s0"?
On one of my laptops, I did have a problem with the predictable naming system not being applied consistently and the networking would then fail if the old (wlan) nomenclature was being used by the system.
When the connection fails, look at the output of:
ip l
dmesg|egrep 'wlp|wlan'Offline

Re: Wifi connection not found
Thanks, Head_on_a_Stick. Interface for wifi is always wlp16s0. Connection did not fail this morning so your test output showed everything normal.
The problem seems to be RF_KILL. The following excerpt from journalctl on today's successful connection shows (2nd line) "toggled to enable radio", after which the netctl-auto connection proceeds satisfactorily, without any termination of wpa_actiond session.
In the unsuccessful attempt "radio" is disabled (4th line) immediately after the firmware reload.
I don't know how to cope with RF_KILL disabling "radio". Isn't that a hardware problem?
