SLOWWWW Network! *SOLVED!*

[BimmerGuy330]

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.

Did you make your own cables, alot of times network problems are caused by poor cables

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.

I am using the nVidia NIC on the XP machine, but it works fine with the other XP computer I have. The Win2000Pro has a PIC NIC.

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!
