[S]Netctl-auto. Default route resets after physical interface restart.
On my lappy i have a button to physically turn on/off wi-fi.
So the problem is when i'm turning it off and then on my connection is restoring with netctl-auto but defaul route is being deleted, ie record "default via 192.168.*.1 dev wlan0" is not longer in "ip route" command output.
In case when i just going so far from one wi-fi ap and getting closer to another one network switches fine and no problem with route.
So do u have any suggestions what am i doing wrong?

Re: [S]Netctl-auto. Default route resets after physical interface restart.
With:
journalctl -fyou can follow systemD logs. Open a terminal, become root and then perform this command. Reproduce the issue and attach the new lines to this post.

Re: [S]Netctl-auto. Default route resets after physical interface restart.
Can you show me the relevant netctl profile config?
Also the output of: 'systemctl list-unit-files'

Re: [S]Netctl-auto. Default route resets after physical interface restart.
Seems like a problem with dhcp. Or, something (wpa actiond) is handling the transition causing the route not to be deleted in the first place.
From what I get it, you should do:
systemctl enable netctl-auto@wlp12s0.serviceThen try again.

Re: [S]Netctl-auto. Default route resets after physical interface restart.
I was already done it initially to make netctl-auto work -- without enabling that it wasn't work at all. Don't know why it's not in 'systemctl list-unit-files' output (mb 'netctl-auto@.service' there is meant to be it), but when i running "systemctl --type=service" i see it:

Re: [S]Netctl-auto. Default route resets after physical interface restart.
Try to enable / disable the service manually. Do this without enabling the service file in systemd and under two conditions:
- without enabling/disabling the rfkill switch
- with enabling/disabling the rfkill switch
I have the feeling the rfkill is doing something the scripts are not expecting.

Re: [S]Netctl-auto. Default route resets after physical interface restart.
Sure:
Prepare for test:
systemctl disable netctl-auto@wlp12s0.service systemctl start netctl-auto@wlp12s0.serviceTest 1:
systemctl stop netctl-auto@wlp12s0.service sleep 10s systemctl start netctl-auto@wlp12s0.serviceDoes internet work? Is the route added?
Test 2:
systemctl stop netctl-auto@wlp12s0.service# disable with switch as well
# wait 10 secondssystemctl start netctl-auto@wlp12s0.serviceDoes internet work? Is the route added?
Cleanup, let's undo what we did:
systemctl enable netctl-auto@wlp12s0.service

Re: [S]Netctl-auto. Default route resets after physical interface restart.
Thanks for explanation, i was confused because u asked to enable/disable so i thought u mean to literally enable/disable unit via systemctl 
So both tests are passing and it looks like i figured out what's wrong -- the timing.
When i tried to reproduce my problem but adding additional 10 seconds between toggling rfkill switch -- all works as intended.
Also i tried to stop/start (not restart) unit without waiting 10 seconds -- and it works for me too.
I suspect the problem was caused by that what route table wasn't cleaned up in time when using rfkill too fast and existed records there somehow disturbing to add new right ones.
So in my case i see the possible solution to drop handling rfkill from BIOS and use systemctl stop/start netctl-auto to turn on/off my wifi.
Thank you a lot for your assistance!

Re: [S]Netctl-auto. Default route resets after physical interface restart.
Maybe you should open a bugreport about this on the ArchLinux bugreport system (netctl is Arch specific I think). It could be that the kernel is taking the rfkill switch more literally than the netctl scripts expect. Furthermore, you might want to look at dhcp timeout tunables if you want to dig further.
Good job though!

Re: [S]Netctl-auto. Default route resets after physical interface restart.
just read releasenotes for systemd 209 and so i noticed what systemd already have systemd-rfkill unit now
so it looks like i should dig deeper into it after the update

Re: [S]Netctl-auto. Default route resets after physical interface restart.
Keep us updated. SystemD is under development as we speak. Furthermore, it has also gained his own network management subsystem as well. Don't know if it's enabled or already available.

They promised it in 209 too. But it said there:
It is capable of bringing up bridges, VLANs, and bonding. Currently, no hook-ups for interactive network configuration are provided.
