Universal Plug and Play (UPnP) allows other devices access the network and connect to other devices as required. UPnP is only available on Windows Me and XP.
It is recommended to switch off Universal Plug and Play on the router if you are not using your devices.
Here is how to enable or disable Universal Plug and Play:
- Launch a web browser from the device
- Type http://www.routerlogin.net. And a login window will open
- Type the routers username and password on their respective spaces. Note that the username is admin and the routers password is the password. Remember that both the password and username are case sensitive.
- Select the advance setup option
- Select the Turn UPnP check box. The checkbox will be automatically selected.
After selecting the Turn UPnP On check box here are the steps to follow:
(a)Type in minutes the advertisement period, this specifies hoe often the router will broadcast the UPnP information.
The values should be between 1 and 1440 minutes. The advertisement period is usually 30 minutes. Long durations reduce the freshness but also the network traffic will be reduced.
On the other hand shorter durations increase the network traffic but the control points receive the current device status faster.
(b) To live type the advertisement time in hops, live time is measured in hops. These are the steps a packet takes between routers. They can range between 1 and 255. The default time is 4 hops which is fine for most home networks. If your device is not being updated or reached correctly it is advisable to increase this value.
- Click the apply button, The UPnP Portmap Table will display the IP address of every UPnP device that is accessing the router and the ports that the device opened either internal or external.
Click the refresh button to refresh the information in the UPnP Portmap table.
