Improve Network Connections with 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),

enable UPnP.



Launch an Internet browser from a computer or wireless device that is connected to the

network.

5.

Select the

Turn UPnP On

check box.

By default, this check box is selected. UPnP for automatic device configuration can be

enabled or disabled. If the

Turn UPnP

On check box is cleared, the router does not allow

any device to automatically control router resources, such as port forwarding.

6.

Type the advertisement period in minutes.

The advertisement period specifies 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 provide current device status at the expense of more

network traffic. Longer durations can compromise the freshness of the device status, but

can significantly reduce network traffic.

7.

Type the advertisement time to live in hops.

The time to live for the advertisement is measured in hops (steps) for each UPnP packet

sent. Hops are the steps a packet takes between routers. 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, it might be necessary to increase this value.

8.

Click the

Apply

button.

The UPnP Portmap Table displays the IP address of each UPnP device that is accessing

the router and which ports (internal and external) that device opened. The UPnP Portmap

Table also displays what type of port is open and whether that port is still active for each

IP address.

To refresh the information in the UPnP Portmap Table, click the

Refresh

button.

Wi-Fi Multimedia Quality of Service

Wi-Fi Multimedia Quality of Service (WMM QoS) prioritizes wireless voice and video traffic

over the WiFi link. WMM QoS is automatically enabled for the router.

WMM QoS prioritizes wireless data packets from different applications based on four access

categories: voice, video, best effort, and background. For an application to receive the

benefits of WMM QoS, WMM must be enabled for both it and the client running that

application. Legacy applications that do not support WMM and applications that do not

require QoS are assigned to the best effort category, which receives a lower priority than

voice and video.
