why so slow?

[David]

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

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

BTW, I've replicated this problem with a cable known to be good. --d

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

David,

Differences between Ethernet and WiFi:
# Network device drivers.
# Network devices.
# Cables.
# Router ports.

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

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.

Do you have current drivers / firmware on network devices? Router?
My router has the latest firmware available as of a month or so ago.

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

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?
