Hello, and thanks to all who have previously posted. Many posts have helped me up until now.
My network has two machines that I'm currently working with. They are:
A) WinXP Pro SP3/Intel Pro 1000 CT Gigabit
WinXP Pro SP3/Marvell Yukon 88E8001
i) Network via WRT54GL Tomato (wired)
I have networked these machines across my LAN and achieved heinous throughput. I have manually set MTU/ACK/TTL etc. on both machines, as well as the router. Making those adjustments seemed to get me nowhere. At first I was stumped, but I went through every setting until I found one that "worked." Unfortunately, I have one issue that I cannot resolve.
As per my normal, I had forced all devices into 10/100 Full Duplex mode, and herein lies the quirk.
A= Intel Pro 1000 Gigabit
B= Marvell Yukon
If all devices are set to 10/100 Full, transfers from A to B are very slow (at most 200 KB/s), but transfers from B to A are nearly full capacity over a 10/100 Full line.
However, if I set A to Auto-Negotiate, my transfers from A to B run at full capacity (or close). B remains forced at 10/100.
Normally, I'd call this good and go with it, but when A is set to auto-neg. my normal internet connection loses 25% of its speed. Obviously, I have tried to get auto-neg. working at its best, but to no avail. It's a small thing to toggle auto-neg. when I want to transfer some files, but I'd love to know what's going on.
I've reached a point where I can no longer tweak any setting that I know of. I'm officially miffed. Can anyone offer a suggestion?
