netctl-auto wireless sometimes doesn't work after booting

Hey,

I have a 50/50 chance to get an internet connection with my wifi card and netctl.
This is what it looks like when it doesn't work:

netctl-auto@wlp4s8.service - Automatic wireless network connection using netctl profiles
   Loaded: loaded (/usr/lib/systemd/system/netctl-auto@.service; enabled)

If it works, the log looks like this:

Any ideas what might be causing this issue?

Re: netctl-auto wireless sometimes doesn't work after booting

I've ran into the same problem a few days ago.
It looks like the dhcpcd timeout is 5 seconds and your wireless card is becoming ready after around 5 seconds (sometimes it takes a little more/less time). Maybe, if you could increase the timeout, this issue would be solved. But I don't know the way, sorry...

If the problem is a timeout, please see the netctl.profile man page.  It is usually good to read the documentation.
