AC1600 WiFi VDSL/ADSL Modem Router Model D6400
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, keep UPnP enabled,
which it is by default.
To manage Universal Plug and Play:
1. Launch a web browser from a computer or WiFi device that is connected to the network.
2. T
ype http://www
.routerlogin.net.
A login window opens.
3. Enter the user name and password for the modem router.
The user name is admin.
The default password is
password. The user name and
password are case-sensitive.
4. Click the OK button.
The BASIC Home page displays.
5. Select ADVANCED >
Advanced Setup > UPnP.
The UPnP page displays.
6. Select or clear 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 modem router does
not allow any device to automatically control router resources, such as port forwarding.
7. Enter the advertisement period in minutes.
The advertisement period specifies how often the modem 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 detect 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.
8. Enter 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.
9. Click the Apply button.
