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, enable UPnP.

To enable Universal Plug and Play:

1.

Launch a web browser from a computer or WiFi device that is connected to the network.

2.

Enter

.

A login window opens.

3.

Enter the router user name and password.

The user name is

admin

. The default password is

password

. The user name and password are

case-sensitive.

Select

ADVANCED > Advanced Setup > UPnP

.

The UPnP page displays.

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 receive 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 should be 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.

Manage Wi-Fi Multimedia Quality of Service

Wi-Fi Multimedia Quality of Service (WMM QoS) prioritizes WiFi voice and video traffic over the WiFi link.

WMM QoS is automatically enabled for the

router

.

WMM QoS prioritizes WiFi 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. Circumstances might occur in which you want to disable WMM QoS.

To disable WMM QoS:

1.

Launch a web browser from a computer or WiFi device that is connected to the network.

2.

Enter

.
