Universal Plug and Play, or UPnP, is an Internet connection setting that allows your device to discover and communicate with other UPnP-enabled devices automatically. If you do not wish to connect your PlayStation 3 to any external devices, you may wish to disable this feature to increase your PS3’s network security. Configuring your PS3 with advanced network settings can allow you to disable this setting.
Turn on your PS3 and scroll to the “Settings” tab in the Xross Media Bar (XMB).
Scroll down and select “Network Settings.”
Select “Internet Connection Settings.” A message will appear informing you that you will be disconnected from the Internet. Click “OK” to continue.
Select “Custom” to configure your own network settings.
Choose either “Wired Connection” or “Wireless,” depending on the type of connection you are using. If you choose “Wireless,” you will have to scan for your network and enter your networks WEP or WPA passkey, if necessary.
Set the Ethernet Operation Mode, IP Address Setting, DHCP, DNS, MTU and Proxy Server settings for your network. In most cases, set these options to “Automatic” or “Do Not Set,” unless you wish to manually configure these options for your network.
Set the UPnP setting to “Disable.”
Select “Internet Connection Test” from the Network Settings option to test that your connection is functioning properly.
