Laptop Fujitsu-seimens amilo L-7300
PCMCIA network card= DWL-G650_revC
Operating System: Windows XP Home

hello, I want some help with the above pcmcia card. fist of all I am a tech
so I know what i am doing... I am using the latest driver only from windows
update, VERSION 5.3.0.46, and NOT the dlink utility I have never installed
the dlink ulility since it creates more problems.

This card has a strange problem with CPU usage, this is very apparent using
the Microsoft utility called process explorer. This is like an advanced task
manager. from there i can see that the hardware interrupts and the deferred
procedure calls are hogging up the cpu making the laptop extremely slow.

see screenshot:

searching Google I have found many people report this same strange behavior
with this card and or other devices...

however many cant find solutions or many have found totally different
solutions..
I have tried almost everything, and I also contacted d-link, but their
support gave me only generic replies that I had tried by my own.
I also tried older drivers, with no luck.

ONE STRANGE THING, is that when I connect to another wireless network in
another location that is slower (11mb) and working in AD HOC mode,
this problem goes away!!!

Please tell me what to do to resolve this issue...

this laptop is freshly formatted and works fine without the card or if its
disabled...

thanks in advance

First off, Windows Update is not a good place to get drivers. The
drivers on there, seem to cause nothing but grief.

I checked the DLink site, and the G650 rev.c download for WinXP looks pretty
old. You should still try it though, in case the older driver does not
have the problem.

The Atheros chipset used in the PCMCIA wireless card is a popular one.
From the PCI.ids file, these are all the products listed using the chipset.
The INF file in the driver download, will contain further information
not listed here. The PCI.ids is maintained by volunteers, and is not
an official copy of the PCI registry.

The AR5212 is the baseband processor chip. A radio chip goes with it, to make
a complete solution. The complete solution is called AR5002X, consisting of
AR5212 (which the driver will reference in its INF as VEN_168C&DEV_0013) and
the radio chip AR5112.

I provided this information, so you could locate a supplier other than
Dlink, that happens to have a later Atheros driver. I looked on the Atheros
site, and they don't have driver downloads.

BTW - I couldn't get your imageshack.us picture to load.
