SLOWWWW Network! *SOLVED!*

I have two computers in my network at home, my main computer with Windows XP Pro, and a second one with Windows 2000 Pro. I have a new Netgear router, with a built in 4 port switch, 10/100. I have a 10/100 NIC card in the 2000, and I'm using the opboard NIC on my XP from my ASUS mobo.

When I try to transfer files from one to the other, I get about 50-100kb/sec. This is simply too slow, and I am wondering why its is so slow. I made sure both NICs were in "100 Full Duplex" mode.....not sure exactly what that does, bu I remember seeing that somewhere before.

If any one had any ideas/comments/suggestions, please let me know! I will provide more information if it will be helpful.

Thanks!

EDIT: Read my last post for the solution.
 
Assuming that your Hardware is functioning correctly try this.

Download DrTCP:
http://www.dslreports.com/front/DRTCP021.exe

Run the program, it will show the current settings of TCP/IP parameters. Write them down.

You can change any variable that you want, click Apply, and reboot the computer, if no good; you can always change to your original values.

Start with:

MaxMTU - DSL =1492 Cable = 1500 DialUp = 576

Tcp Receive - 255552 (This is the varaible to play with!)

Window Scaling - Yes

Time Stamping - No

Selective Acks - Yes

Path MTU Discovery - Yes.

Black Hole - NO

Max Duplicate - 2

TTL - 64


 
Update: I hooked up another computer using the same cat5 cable, and it worked fine, with ~5MB/sec, so I know it's not a problem with the cable. I downloaded that program, and ran it on the "slow" computer (windows2000pro), and it had no effect on the speed. One thing: in hte program, you can select which adapter to change the settings for. I picked my NIC, but there were many otehr choices, and they were all "PPoE Ethernet Adapter". There was like 5 of them....not sure why they are there? Maybe it is trying to use these instead of the NIC? Anyone know how to check?

Also, when I open up the LAN connectino box, it says "100 MBPS" as the connection speed.
 
Are you using the Nvidia NIC? I take it this is an Nforce2 board?

I found the Nvidia nic to be slow and I am using the 3com one. With the Nvidia nic I was getting like 1Mbps on a 100mbps network. With the 3com I am hitting my peak of about 50Mbps.

 
Ya I had issues with the Nvidia nic going to a Win2K machine from a WinXP machine. I just use the 3com nic now.
 
I really doubt it's the specific NIC brand, I have a nVidia chipset board, the EPOX 8RDA, and it's behaved itself just fine with W2K running on it. I have Netgear, the EPOX, and the Realtek NICs, and all of them work just fine in my LAN.

BINGO! Thanks so much Genx87, that solved it! I wouldn't have guessing something like that would have been the problem...but now it works fine! I just switched from the nVidia to 3Com NIC on the XP machine, and it works fine now.

Thanks also to everyone else who gave input!
