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/[email protected]
[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 [email protected] as root. Change wlan0 to the required network interface.
