But that's only if either endpoint is stuck at a 64 KB receive window. A

I apologize I should have said it starts out about 3 meg max and slows to about
400kpbs for most of the transfer.

Sounds like a combination of packet loss and small TCP receive windows. If
you can, grab a packet capture and make sure to get the TCP setup. That
should show you what's happening under the hood.
Also, I should mention that I totally hosed the units in my first reply.

Recommendations:
1) Use iperf in TCP mode to test the performance
2) use iperf in UDP mode to test the performance
This is the best way to quickly triage the issue and determine if
it's actual bandwidth issue or something else.
