TCP Out of Order Packets? Help!

[Ansar Mohammed]

This typically happens with an old card/new switch or new switch/old card. 
Turn off auto negotiation on your cards on the Linux/OS/2 and force
FastEthernet (100Mb/s) If you can do duplex then go for it.

Subject: [TLUG]: TCP Out of Order Packets? Help!

I have a home network, connected with an SMB Barricade router. I have a 
10.1 Mandrake Linux machine, and OS/2 (eCS) machine, an XP Desktop and 
an XP latop.

When transferring data from either XP box to either the Linux od OS/2 
box I get terrible performance.

When transferring data to an XP box, I get expected performance for a 
100mps LAN.

I am using ftp, to try to keep things as simple as possible while 
analyzing the problem (but I want to start using SAMBA as a fle server.

Since the problem occurs regardless of whether the ftp server is on the 
linux box or the OS/2 and from either of the XP boxes, I am guessing 
hardware is not an issue.

I ran netstat on the OS/2 box (I am still more comfortable in that 
environment) and found that 60% of the TCP packets were out of order!?

For a simple LAN this seems absurd. Is this the cause of the bad 
performance?

If so, how do I fix.

Thanks for any and all help!
