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.
To enable Universal Plug and Play:
1.
Launch an Internet browser from a computer or wireless device that is connected to the
network.
2.
Type
or
.
A login screen 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 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.
