This systemd script restarts Network Manager when resuming from suspend.
#!/bin/sh
MYNAME=$0
restart_network() {
/usr/bin/logger $MYNAME 'restart_network BEGIN'
systemctl restart NetworkManager.service
/usr/bin/logger $MYNAME 'restart_network END'
}
/usr/bin/logger $MYNAME 'case=[' ${1}' ]'
case "${1}/${2}" in
hibernate|suspend|pre*)
;;
resume|thaw|post*)
restart_network;;
esac
You’ll need to create this script, called network-reset, with sudo powers and save it into the directory /lib/systemd/system-sleep. Then mark it executable using:
chmod a+x /lib/systemd/system-sleep/network-reset
The logger commands above allow you to audit results by running journalctl or by looking in /var/log/syslog.
