Most routers by default this is disabled the function of demand, so the question of how to enable uPnP, a home ne

twork administrator urgent.For example, in network devices of D-Link (refers to expensive models as uPnP is supported only on them) to activate this feature can be when you select Advanced.The administrative panel of the router can be found at the gateway (the command ipconfig / all in the console) and go to it via a standard browser (after finding out the password from the default router).

But if there are no system files, UPnP Test Program is unlikely to help.To restore them, you must manually reinstall the components of Windows - "Discovery and Control Client Gateway Device" and "User Interface UPnP".At the same time, check whether the built-in firewall, disable the service.Is a great way to learn how to configure UPnP.After the completion of these procedures, be sure to reboot the PC.So you learned how to enable UPnP.
