Section 7-2 - Diagnostics
The Network Test will test DSL or cable internet connections, which operate within a network
environment. However, this test does not test the DSL or cable modem used for accessing
the Internet. Currently, no PC-Doctor test exists for testing cable or DSL modems.
The Network Communications Test checks if your PC's network card works and if your PC
properly communicates over a network. It makes a list of all the remote PCs on the network that
the NIC uses and sends information in the form of several “data packets” from the tested PC to
the “host” PCs. These “data packets” are then returned by the “host” PCs to the tested PC where
the contents of the “data packet” are checked. If too many of the “data packets” fail to get
returned or are thrown away because of data corruption, the Network test logs as FAILED.
