+plugin: manual
+_summary: Connections managed by NetworkManager should come back when device wakes up
+_purpose:
+ When a device goes to sleep NetworkManager disconnects all connections but
+ will reconnect them back when the device reawakens.
+_steps:
+ 1. Verify the device is connectd to a WiFi or ethernet network. You can use
+ .
+    $ network-manager.nmcli d
+ .
+    to check if a wireless network interface is connected or not.
+ 2. Suspend the device by calling
+ .
+    $ systemctl suspend
+ .
+ 3. Wake up the device again by pressing its power button
+_verification:
+ When the device comes back from suspend after pressing the power button
+ verify with
+ .
+ $ network-manager.nmcli d
+ .
+ that the previously connected WiFi/ethernet network is again connected.
