N750 Wireless Dual Band Gigabit Router WNDR4300

USB Settings

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

Specify Approved USB Devices on page 54 for the procedure.

Universal Plug and Play

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.

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.

• UPnP Portmap Table. The UPnP Portmap Table displays the IP address of each UPnP

device that is currently accessing the router and which ports (internal and external) that

device has opened. The UPnP Portmap Table also displays what type of port is open and

whether that port is still active for each IP address.
