Diagnostics
To check the link status for the network and your computer, a diagnostic test can guide you to detect
the network problem. The testing items are listed and accomplished one by one. If the previous one
is failed, than the items below that failed one will be failed too. Use this diagnostic test to detect the
connectivity mistakes whenever you happen to the linked problem.
For the item which passes through the
diagnostics, a PASS word will be shown on
the right side of that item.
If not, a Fail word will be there.
N/A means that item is not necessary for the
system to test.
The Help link lets you know what the result
(Pass, Down, Fail) represents for. In this
page you still can rerun diagnostic test at any
time.
