durations ensure that control points have 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 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.
9. 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, both it and the client running that application must have WMM
enabled. 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 a web browser from a computer or mobile device that is connected to the
network.
2. Enter http://www.routerlogin.net.
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.
The BASIC Home page displays.
4. Select ADVANCED > Setup > QoS Setup > WMM.
The WMM page displays.
5. Clear the Enable WMM (Wi-Fi multimedia) settings (2.4 GHz b/g/n) check box.
