Network: Peer to Peer
OS: Windows 2000
Router: Linksys BEFW11S4 10/100
NIC: Realtek RTL8139 10/100

In this setup ideally the network transfer rate should be 100MBits per second. However, The computers are transferring to each other at no more than 3.5Mbits per second.
I have tried the following:
1. Disconnected all computers except two computers to transfer.
2. Tried a different Ethernet card.
3. Tried using a HUB with Windows 2000 Adv Server as DHCP Server.

A solution to get this network up to par configuration would be greatly appreciated.
Par = At least in the 50 to 60MBit level.

Thank you

It sounds like the entire issue could be hardware related, for both the speeds of the Router and the NIC...in the succession of the link from NIC to ROUTER to NIC and Router again, over and over, etc, any kind of bottle-neck can slow your entire traffic flow down. Because in your peer to peer situation, the Router is just going to grab those packets and send them over to that other PC, or set of PCs...simple delivery (this is for you, here you go...simple hand off).

You should be able to find a diagnostics utility for maybe just the Realtek NIC, or possibly both. Do some testing with this utility to see exactly HOW it is sending packets of data on your peer to peer and at what ACTUAL speeds.

NIC's are getting better all the time,but most of the ones I have dealt with (10/100 3com) come configured at 10MBits/sec right out of the box.

Good luck!

I have ran tests with the Realtek transmitting to another Realtek and clocked in its actual speed at 3.5mbits then i benched the same Realtek with a Linksys NIC and got the actual speed at 1.3mbits additionally i tried a linksys to linksys NIC and clocked it in at 2.8mbit. either way im under a 10mbit level. So I apologize your solution was not workable.

Maybe the auto detect on your nics are not quite matching each other correctly.
Right click My Network places - right click Local Area Connection- click properties - on the Advanced tab choose configure - select Link speed and duplex in the property box and under value change the setting from auto detect to full duplex for either 10mb or 100mb.

This should improve your transfer speed.

Hope this helps

thanks....but i fig'd it out....nothing to do with the brand of NIC, nor the auto negotiation....or the duplex....... since you'll even bothered too look....u get a cookie....=P

While Linksys and Realtek do work, they aren't exactly the top of the technology chain. OK, some would argue that. But the duplex mismatch is a good thing to check. Autonegotiation is a wonderful thing, when it works. The speed is not the issue,it's the duplex. When one is half and the other is full you have problems. Verify the negotiated settings at both ends.
