Rebooting a Router
A router is rebooted by the popup-menu of the respective router node in the navigator frame:

The router waits 10 seconds after executing the command, then it shuts down all swiftlets. The router process will not be closed. After the Swiftlets shutdown, they restart automatically. The node in the navigator frame disappears during the reboot temporarily, then it appears again.
If changes are made concerning the configuration which require a reboot, these changes are active now if the configuration was saved before.
