Wireless slowdown problem

Hi,

Firstly apologies if something like this is already on here. I've had
a good look through and can't find anything so here goes,

For some reason my wireless connection seems to slow down over time.
What i mean is that immediately after turning my machine on, my network
connection whizzes along fine, then about 10-15mins later browsing and
downloading is reduced to a crawl, download tests (through a network
card traffic monitor) says 2kbps, when it first connects i get 3.6mbps.

My machine is an athlon 64 3000+ running at 1.3GHz, 1 Gig of RAM with
XP Pro SP2 (fully updated, not the x64 version though). The machine
runs fine, apart from the internet connection. I was using a Netgear
Range max wireless usb dongle (WPN111GE) and thought that might be the
issue. I've just installed a D-link 53Mbps pci card (DWL-G510), hoping
that would solve the problem, but exactly the same thing happens.

The router is a 54Mbps dsl netgear one (WGR614, with latest firmware
on) and that is connected to a virgin cable modem via ethernet.

This problem only happens on my desktop PC. When i connect it directly
using a huge long ethernet cable, I don't have a problem. My laptop and
my three housemate's laptops don't have any problem either (They are all
running XP SP2 as well).

I'm running Avast antivirus and switching it off has no effect, nor
does turning off the windows firewall.
If i disable the wireless card then re-enable it, it seems to sort
itself, then slows up again. I'm thinking is must be the hardware, but
to happen to two different bits of kit from different manufacturers is a
bit weird. It is the same issue in IE7 and firefox.

I've tried flushing the dns cache and in the event viewer is said i was
reaching the maximum TCP/IP connection limit, so i have patched that and
increased it to 40 (from 10). No luck. I have done a system restore to
a point when i thought it was ok, a couple of months ago but again, no
luck.

And i have tried turning everything off and back on again. A lot.

Any help would be massively appreciated, cheers

Let me guess -- you're running a filesharing client?
