Is there anyway to make a wireless PCI network card stop hogging the CPU?

How does a card hog CPU ?
My task manager only shows processes using CPU. If there is a process
talking to the card and it's using a lot of CPU, you could lower its
priority if you think it won't have adverse affect.

Sure, if you are the designer, there are three things: chipset, firmware,
and driver.
For the rest of us, the best you can do is pick a card which does not hog
the CPU. Generally, the fastest cards do more work right on the NIC so there
is less for the CPU to do.
Which card/OS/system are you having trouble with?

And which card is that?

Same question.

Don't know, but you should check the docs for each card and see what the
description says. We had cards years ago that were called smart cards
that did much of the TCP/IP work on the card (which had its own CPU and
was downloaded with firmware on system startup).
Today's CPUs are so fast that I wouldn't even bother paying the extra bucks
for a smart card (we were running like 286's back in those days and it made
sense at the time). I would think 3Com would have smart cards and you probably
pay at least quadruple for them since a reg card is like $10-20. They'll offer
remote management, processing offload features and the like.
The NIC shouldn't be hogging the CPU unless you either have negligible CPU
or extremely high network traffic. I would check both first. See what the
CPU is like with the network disabled and see how much traffic you have
with the net enabled and a monitoring tool checking the traffic load. You
can get a little info from the Task Manager Networking tab (on XP and the
like for example). I seldom go over 1% network utilization unless downloading
which still stays under 10% since it's WB (not local LAN).
