LAN/NIC problem

[MarkHaysHarris777]

You are apparently not aware of cross-talk.  I suggest you read up on it, because it dramatically affects this particular hardware problem.

Seriously? <snip> I haven't seen any evidence that would suggest that length is an issue. Earlier in this thread, the second poster indicated that this was not the case in relation to his issue, as neither long nor short Cat6 cables made any different.

You are mixing ( and again, confusing ) this conversation.  No one ( not me ) said the issue is the length; that is both a red herring and a straw man argument at the same time.

All that I said, and all that I meant, is that changing the length of the cable 'has in fact' changed the measurable out-comes in this situation (that's all !).  And it is measurable and it is repeatable !

That's just science bubba.

There is a very good write-up in the link I posted earlier about the inherent problems in twisted pairs with cross-talk and how the hardware (and software) at each end are employed to negate the noise.  This is especially true with GbE (which is why all eight wires, all four pairs) are necessary.  

The issue IS NOT the length of the cable; however, the length of the cable has made a difference in the measurements made in relation to this thread. It should also be restated that the inconsistent and intermittent results obtained in the measurement process are very much indicative of a hardware problem; at this point I am almost 100% sure that the situation is hardware only at its root cause.
