network diagnostics failing

[Guest]

when I run network diagnostics it fails on my network card because it cant
ping the IP address of the machine Im runnning the test on. I've also
noticed that my fan runs really fast when Im using a network heavy
application like browsing or AJAX-heavy web apps.

Any suggestions?
Thanks!

Hi
This might help in diagnosing the Network, http://www.ezlan.net/debug.html
When the Laptop works "Hard" the CPU get Hot and the fan kicks in. that is
the way it suppose to be.
In addition you want to check the Laptop's ventilation system, if it is
clogged with dust, it gets even hotter.
I do not what is the make of your Laptop, but this page describes the issue
with a Sony VAIO, http://www.ezlan.net/vaio.html
