XP to XP slow data transfer

November 10, 2009 at 05:44:11
Specs: Windows XP, P4 / 4G and P3 / 2G
I have two XP sp3 machines in my network. Data transfer between them caps at 1Mbps. This is very odd since both machines have tested at speedtest.net at 15M down and 1M up. Why is my network transfer so slow? What can i try.

A little about my network. All cable is new cat 5. There ere 10/100 NIC in each machine set to 100 Full Duplex. I have tried setting the NIC to "Auto Negotiate" with no success. Both machines have static IP's assigned. All anti-virus and firewalls are off. Both machines are on the same workgroup and can see each other.

Cable modem connects to a Linksys WRT54GP2 router with built in 10/100 switch.

Machine "A" connects from router through a set of Netgear HDX101 Powerline HD Ethernet Adapters then to the machine.

Machine "B" connects directly to the router via cat 5.

I also have a MacBook on network too. It's wifi also suffers from the same transfer rate. If the xp-xp fix doesn't also fix the MacBook i will open anew post about it.

Try connecting the two machines NIC to NIC with a crossover cable.

As to what is wrong, that's very hard to say. It's extremely odd that "autonegotiate" isn't working but as long as both are set to 100 Full Duplex and any/all devices between them are also 100 Mbps (or better) then they should be able to transfer data at around an average of 80 Mbps.

Perhaps you're having hardware problems. It's extremely hard to say. All I can tell you is if this were my network I would first connect the two with a crossover and do a transfer. If it still crawls, then the issue is one NIC or the other. If it transfer's fine, that rules the NIC's on the PC's out and leaves only the hardware in between the two to be tested to find out which one is the problem.

I dont have a cross-over cable but i did read somewhere that modern NIC can auto determine a cross-over cable setup and use any cat 5 as a cross over. Is this true, will it work?

It does work.. just still at 1Mbps

"Machine "A" connects from router through a set of Netgear HDX101 Powerline HD Ethernet Adapters then to the machine."

Netgear says these can do 200mbps. I don't believe them.

Well duh! powerlines are usually 10mb or less! Apparently less! They depend on your house ground wiring. Poorly terminated grounds have all sorts of issues.

This is why you get 1mb. Bet if you moved the powerline pc and plugged directly into the router you would be at 100mb.

BTW your upload/download speed have nothing to do with lan transfers.

"Well duh! powerlines are usually 10mb or less! Apparently less! "

Well s---! and thanks. i thought this may be it. I'm in a new building (10 years) so the wiring should still be good. Im also on the same breaker power network.

I guess i just don't get the Mbps numbers. Why does it say 200Mbps but only offer 1.

Im gonna try wireless transfer and see if it gets better. brb.

I have tried bypassing the Powerlines and transferring the data over WIFI. I only get up to 1.5 MB/s transfer speed. My WIFI says im getting 54 MB/s. I was hopping to see near 25 at least. :(

So now what could be tried?

what do you get when you directly connect to the router?

How many walls between the pc and the router?
signal strenght?
Using a wireless usb dongle on the pc?

I cant directly connect unless i move my workstation (not happening). There is one wall between me and wireless router. Wireless signal is good (54Mbps). Yes im using a wireless dongle.

I missed the bit about running over power lines. I agree with wanderer 100% on this not being a very good method.

I also don't care much for wireless. I highly recommend connecting via a network cable to the switch and then trying the transfer as wanderer suggested. Report back to us and let us know how it goes.

No, this won't work. You have to use an actual crossover cable. Try connecting to a router directly and if you still get slow speeds, look into borrowing, or buying, a crossover cable and use it. Before you do, ensure all NIC's are set to autonegotiate.

One wall? Pretty easy to run a cable unless its a concrete or brick wall.

If your signal wasn't all that hot there is a you tube video on using a quart metal strainer to increase signal reception.

The wall is a floor and its concrete. My wireless signal is fine.
