Uneven Transfer Speed on Network

I have two WinXP SP2 machines networked via a wired D-Link router (DI-604).
The network is running at 100 Mbps. If I try to transfer a file from machine
A to machine B, the transfer rate if fine (20M in about 10 sec). However, if
I transfer the same file from machine B to machine A, it takes about 20
minutes.

Has anyone seen this before and know how to fix it.

Larry,

Are both computers connecting at 100M / Full Duplex? I've had uneven transfer
rates before I got all my computers connect Full Duplex. The DI-604 should show
which ports are connecting in FD mode.

Cheers,

Paranoia comes from experience - and is not necessarily a bad thing.

Thanks for the input Chuck, but I set both computers to 100 Mbps / Full
Duplex and it didn't help. I also tried swapping out the cables and changing
the ports on the router, but no luck.

Any other ideas

Larry,

Do the lights on the router actually indicate that you're connecting at 100F?

Are you using the latest drivers for the network adapters?

With XP, you can look at the Networking tab in Task Manager, and see if there's
a network bottleneck. The Processes tab will show if there's a processor
bottleneck. And check the hard drives on both computers, make sure that neither
is full, and is fully defragged.

I've had fragmented Usenet group files slow down my news retrievals before.
Defragged, and performance picked up. Shouldn't take too much fragmentation to
make a 100MB LAN connection outrun a fragmented hard drive.

Cheers,
Chuck

Larry,

you could fill in the form in
http://www.michna.com/kb/wxnet.htm, probably just by selecting
the "slow" choice, then read the solutions.

Thanks again
I have a DI-604 router model C, which doesn't report on the port settings.
The lights just show that the connection is active, but not therate.

I'll look into updating the card drivers

Network tab shows 100 Mbps with no bottle necks

And the disks have plenty of room and not very fragmented.
