The UPnP screen displays. 
5. 
Select the Turn UPnP On check box.
By default, this check box is selected. 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.
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.
To disable WMM QoS: 
1. 
Launch an Internet browser from a computer or wireless device that is connected to the 
network.
