I incrementally added the suggested CN values and rebooted.  The only value that I did not use was the NaN value for the DefaultSendWindow.  Instead, I used 98304.  I did not receive runtime errors, this time.  All appears to be working.

Here is the latest TCP/IP Analysis:
~Snipit~ SpeedGuide.net TCP Analyzer Results

~End Snipit~

I would like to ratchet up the Upload side toward the 768 advertised speed.  Can a CN setting do this?
