The Universal Plug and Play (UPnP) architecture is a set of protocols that allow devices, such as PCs, home electronic or wireless devices, software applications, etc. to be automatically configured as part of a network and be ready to work (i.e. to play), as soon as these are connected (i.e. plugged). For a device to be UPnP compatible, it should be able to join a network dynamically, i.e. to obtain an IP address, open the required ports, and learn about the presence of other devices, all automatically. When the device is disconnected (i.e. unplugged), its network details should be automatically removed from the router’s listings.
As the UPnP function is supported by most Windows OSs, the UPnP setting in Vigor routers allows full compatibility for the voice, video and messaging features of communication applications such as MSN, Skype Talk, etc.
Below are some notes about UPnP function:
- Some Firewall applications, e.g. Windows Firewall, may block network ports and prevent the UPnP function from working properly.
- You should ensure that your Windows OS has the latest service packs and patches.
- UPnP allows any users to plug in unspecified devices and control certain router functions, e.g. removing and adding port mappings. This may or may not be desirable for your network.
- When the devices are unplugged, the port mappings may or may not be removed accurately.
- If you enable UPNP but do not enable the Connection Control and Connection Status service, you will not be able to see the connection status or disconnect/ connect Vigor router’s WAN connection.
