UPnP :
Universal Plug and Play (UPnP) is an architecture for pervasive peer-to-peer network
connectivity of PCs and intelligent devices or appliances, particularly within the home. UPnP
builds on Internet standards and technologies, such as TCP/IP, HTTP, and XML, to enable these
devices to automatically connect with one another and work together to make networking -
particularly home networking - possible for more people.
The UPnP aware applications such as MSN Messenger will discover that they are behind a NAT
router, learn the external IP address and configure port mappings on the router to forward
packets from the external ports of the router to the internal ports used by the application.
3.4.3.6.8 Diagnostic Test
As soon as you enter the test program, all tests will run automatically to diagnose the connection
status of the device.
Checking LAN Connection
Testing Ethernet LAN connection
This test passes if the Ethernet LAN interface is working properly.
Checking ADSL Connection
Testing ADSL Synchronization
This test checks your DSL modem to see if it can successfully negotiate and establish a DSL
connection with your service provider's central office equipments. The test returns PASS if a
DSL connection is established.
If this test returns FAIL, please try the test again a few minutes after this test is
completed. Since your DSL modem need a couple of seconds to a few minutes to establish
the DSL connection depending on your phone line quality. If this test returns FAIL, make
sure your phone line is connected to your DSL modem securely, and also check with your
service provider to see if your service is activated.
If this test returns FAIL, all other tests will be skipped.
