I've got two XP machines on my home network (linksys wrk54g) that I'm
moving ~14Gb of data between. Now, I don't expect the full 100Mb/s
throughput but it seems to be exceedingly slow. In about 12 hours, I've
moved around 1.9Gb which comes to about .337Mb/s.

Any ideas what the problem might be?

TIA,
David

David,

Your question comes up occasionally.  Copying files form one computer to another
is a complex procedure, though it may not look that way to you.

Please start with my article on diagnosing network problems.
<http://nitecruzr.blogspot.com/2005/08/solving-network-problems-tutorial.html>
http://nitecruzr.blogspot.com/2005/08/solving-network-problems-tutorial.html

Now if you have a WiFi network, are the computers connected by Ethernet, or
WiFi?  If both are using WiFi, then you have a duplexing problem.  This is a
relevant detail, which is needed immediately.
<http://nitecruzr.blogspot.com/2005/06/background-information-useful-in.html>
http://nitecruzr.blogspot.com/2005/06/background-information-useful-in.html

Besides the physical connectivity possibilities, there are protocol problems,
and possible performance problems on the computers themselves.  But as I like to
diagnose problems in a layered sequence, let's concentrate on the physical
network first.

Thanks Chuck. Your notes seem to address situations of NO comunication
bw computers. As I said, I have a connection, it's just very slow. FYI,
in an attempt to transfer the data faster, the two computers (one
desktop and one laptop) were wired via Ethernet.

I can mount my shared drives just fine bw the machines. My issue is
throughput.

Any thoughts?

TIA,
David

Unbelievable...I just 're-connected' the computers (wirelessly) and
find that I'm now on track to move 12+ Gb of data in < 2hrs! What's it
take to predict throughput?!?!?

So, it's interesting that I was having the problems wired but not
wirelessly. I'll test the wired again after this transfer is complete
and report back the findings.

Geez!

New observation: The files I'm moving are music files. I notice that
the time estimate for the transfer increases considerably when I start
WMP. Might this have been related to my problems? Mind you, the files
that were moving slowly were NOT being played but WMP was up and
running.

Thanks again,
David

I've confirmed that the problem is when I'm connected via Ethernet.
Wirelessly, I'm fine.

Any thoughts what it might be then?

Thanks again,

David,

Differences between Ethernet and WiFi:
# Network device drivers.
# Network devices.
# Cables.
# Router ports.
<http://nitecruzr.blogspot.com/2006/06/layered-testing-in-windows-networking.html>
http://nitecruzr.blogspot.com/2006/06/layered-testing-in-windows-networking.html

When you connect Ethernet, do you do both computers by Ethernet?  WiFi?

Do you have current drivers / firmware on network devices?  Router?

Inventory network equipment (make / model), and how everything connects.

Please see my network topology at
http://www.drschwartz.net/personal/network-topology.jpg
As you can hopefully see, T42p connects wirelessy as well as through
Ethernet. There's also another Dell laptop that occasionally connects
wirelessly that's not shown. Everything else is Ethernet. Please note
that the problems I've been describing are between Office and T42p.

Please see the diagram above. As I said before, your content appears to
focus on lack of connectivity rather than limited throughput. Is this
correct?
Thanks so much for your help on this Chuck!
