Problems with netctl-auto on resume
Sometimes netctl-auto fails to reconnect when the system resumes from suspend. An easy solution is to restart the service for netctl-auto. This can be automated with an additional service like the following:
/etc/systemd/system/netctl-auto-resume@.service
[Unit] Description=restart netctl-auto on resume. Requisite=netctl-auto@%i.service After=suspend.target [Service] Type=oneshot ExecStart=/usr/bin/systemctl restart netctl-auto@%i.service [Install] WantedBy=suspend.target
To enable this service for your wireless card, for example, run systemctl enable netctl-auto-resume@wlan0.service as root. Change wlan0 to the required network interface.
