Netgear WNDR3700V4 사용자 설명서

For added security, the router can be set up to share only approved USB devices. See 

54 for the procedure.

Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, 
access the network and connect to other devices as needed. UPnP devices can 
automatically discover the services from other registered UPnP devices on the network.

If you use applications such as multiplayer gaming, peer-to-peer connections, or real-time 
communications such as instant messaging or remote assistance (a feature in Windows XP), 
you should enable UPnP.



Select Advanced > Advanced Setup > UPnP. The UPnP screen displays. 

The available settings and information in this screen are:

Turn UPnP On. UPnP can be enabled or disabled for automatic device configuration. 
The default setting for UPnP is disabled. If this check box is not selected, the router does 
not allow any device to automatically control the resources, such as port forwarding 
(mapping), of the router. 

Advertisement Period. The advertisement period is how often the router broadcasts its 
UPnP information. This value can range from 1 to 1440 minutes. The default period is 30 
minutes. Shorter durations ensure that control points have current device status at the 
expense of additional network traffic. Longer durations can compromise the freshness of 
the device status, but can significantly reduce network traffic.

Advertisement Time to Live. The time to live for the advertisement is measured in hops 
(steps) for each UPnP packet sent. The time to live hop count is the number of steps a 
broadcast packet is allowed to propagate for each UPnP advertisement before it 
disappears. The number of hops can range from 1 to 255. The default value for the 
advertisement time to live is 4 hops, which is fine for most home networks. If you notice 
that some devices are not being updated or reached correctly, then it might be necessary 
to increase this value.
