diagnosis problem

[AG]

Hi all,

I have a PCMCIA card (WPC54G v3 linksys wireless-G notebook adapter)
used for my internet connection. I have a dual core processor with
Windows XP sp2 uptodate. I installed my wireless adapter on the
notebook and got internet connection easily. But the CPU usage showed
by the task manager was indicating me 50% (one of the two processors
used all the time), while, at the same time the idle process was using
99% of the CPU. Googleing across the web, I downloaded "Process
Explorer" which is like the taks manager, but with a little more
details. It showed me that most of the CPU usage came from hardware
interrupts. As a matter of fact, when I take off my network wireless
adapter, the CPU usage drops down to almost 0%. And when I put it
back, the problem comes back.
Googleing into this a little bit more, I see that disabling
peripherals one by one would pinpoint me the culprit. As I know it is
related to my adapter, I sucessively disabled all peripherals linked
with the adapter. I even disabled the hidden peripherals. But the
problem stayed. once all my peripherals were disabled, I shutdown my
computer and when it came up, of course, the problem was gone. There
is around 10 peripherals related with the adapter, and
disabling/enabling a peripheral takes some time. If in addition to
that I have to do a power off power on each time I test a peripheral,
it will take me hours. Would you have any hint on this ? Any tool that
could help and go into more details into the hardware interrupts ? Any
method to track this problem down would be much appreciated.

Of course, I forgot to say I have updated all the drivers from linksys
website. And I also tryied to disable all the running services I
could, but none of the stopped services could stop the hardware
interrupts problem.

Alexandre.

I think you should be dealing with Linksys tech support since it is their
hardware causing the problem--the adapter may even be faulty.

It might also be working correctly. If you've inherited an IP address
that had recently been used by someone doing file sharing (say) then you
may very well be being bombarded with IP requests.

Do the interrupts stop if you unplug the network cable?

I have a linksys wireless router with and a dynamic IP. At home, my network
is configured using DHCP. the IP of the notebook is always the same
(192.168.0.2). I have a second computer, that also is connected to the
router using a wireless connection (PCI card) and that is running without
any problem. I have a firewall configured. If I were bombarded with IP
requests, my firewall router would intercept them, and if it were not, there
is little chance requests would have been transfered to my notebook only.

Thank you anyway for trying. I think I will try dealing with linksys people.
