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 http://www.routerlogin.net or http://www.routerlogin.com.

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 modem router resources,
such as port forwarding.
6. Type 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 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
