Are you able to get your wrap into the 100kbps state, and then measure 
packet loss through it instead of just raw transfer rate?
I have a wrap 2eth/2minipci I can run through a climatic testing chamber 
(though I'll have to ask the owner of the wrap first).
My guess would be that you see packet loss on one or both interfaces.

Second, do you live next door to a powerful RF emitter? I have a smallscale 
EMC lab too.
On the WRAP I have here the corner screw holes are connected to GND, and the 
ethernet connectors are well decoupled to GND too. A nearby RF emitter and 
UTP cable just _might_ cause problems (since then the rf decoupling isn't 
connected).
