Thanks for the reply. Answers as follows:

What router and wireless [makes and models]?

The router is a Netgear DG 834G. The wireless card in the newer model
I'm not sure about, but as I said in the first post I've eliminated
wireless from the problem by connecting both computers to the router
with ethernet cables.


*You indicate Wi-Fi for the XP, did you try with the XP connected via cable
to the router?

Yes


*Are you using mapped drives and transferring via Explorer? IF so which OS
is the transfer master?

I did the transfer by clicking on "My computer" on the XP machine and
dragging and the dropping the file from "my network place" to the
directory I wanted it in.

Did you check for adapter settings such as:
Flow control;
Media Type, etc..

No, I'll see if I can find these settings, although I don't know what
the best settings would be.


You said you disabled the firewall, was that on both machines?

I didn't disable any firewalls, only the antivirus on the XP machine.
The win98 machine doesn't have any antivirus software, nor to my
knowledge a firewall, unless firewalls were an integral part of win98?

Thanks for any further advice.
