If you notice that a PrivateRouter service like DLNA, SAMBA or OpenVPN is not working correctly this can usually be resolved by doing the following:
1.) Reboot the router
-or-
2.) Restart the service manually
For example, if DLNA is not updating recently added files on a USB drive you should restart the DLNA service.
Under the System tab click the Startup option and locate the service name that is giving you a problem.
Click the Stop button next to the service name, then click the Start button. This usually resolves any temporary issue without the need to reboot your router.
