Why is copying data between my 2 computers VERY slow?

Hi

Copying data on to my new Windows7 PC (from my old PC) seems EXTREMELY slow.
For example copying about 1.5GB of various data files takes over 50 minutes
(claimed speed c.500KB/sec)
However I have a new-ish "good quality" Router and the network adapters
for both my PCs claim to be running at "100Mbps/Full Duplex".

My configuration:
1. WindowsXP machine (3 years old)

MOTHERBOARD: Intel Pentium 4 D945GNTLR system board 3.2GHz
Network Adapter: Intel PROSet version 14.7.23.0
Adapter Speed setting: 100Mbps/Full Duplex (Autodetect)

2. Router: (1 month old)

Make: Thomson TG585 v7

3. Windows7 machine (1 week old)
Motherboard: Intel DP55WB MA TX
Processor: Intel Core I5 750 2.66GHz
Network Adapter: Intel 82578DC "Gigabit Network Connection"
Link speed status: 100Mbps/Full Duplex (manually set)

Why is it running so SLOWLY?
Do I need to do something to the router to speed it up?
Cheers

Have you tried Pinging the router from your PC to see if any packets are lost?

Test a TCP/IP configuration by using the ping command: TCP/IP

Have you tried to reset the router yet?

I dont know what slow is.. everything my house is gigabyte thats cause i network LAN parties....

umm umm see the thing is that even though you have 100 mb lan, it won't use it all of it.

your switch and router has some very big things about it too... this is what i did..

I have a switch that is 10/100/1000

everything is pluged into the switch and my router is on the outside.

i dont router anything through my routers LAN ports except LAN 1 goes into the switch to make it functions work

that way if the router goes down the switch is still up and running.


How did you set your system up..... we may have to open up some ports, check your firewall... umm someimes if you have antivirus and your transfering files, it problem is checking them while it goes out.. posiblity

Sorry I'm not completely sure how to test using Ping - (but it looks roughly okay to me).

Yes I have turned the router off (for 30 seconds).

I just found something that might be of some help:

Slow Network File Copy issues in Windows 7 caused by Remote Differential Compression | Windows Reference

It relates to a compression feature in Windows 7. You could give that a try and let me know if it makes a difference.

Yes Remote Differential Compression was set on.
No, turning it off didnt make any difference.

1.5GB took 50 minutes, that is pretty slow. I can usually do 20GB in about 15 minutes or so. I never had to do anything special to my network just to transfer files and the firewall ports are opened up automatically when you set up file sharing. Is there an echo in here LOL.
