I got to test out the changes made above, specifically:
"
Edit - Control Panel\All Control Panel Items\Network and Sharing Center\Advanced sharing settings - There are three options at the top of each section to turn on/off "network discovery," "file and printer sharing," and "Public folder sharing." I had to set up a new network for this modem and just disabled these three. The "ndis.sys" driver is still #1 on the LatencyMon list, but significantly lower, and all of the "spiking" went away."
Although LatencyMon registers the network, there is no adverse affect to having the internet connected or even running. To stress test it I actually recorded real-time off YouTube and all was well. It seems "
Automatic Network Discovery" is the ultimate problem child here, and is really an unnecessary function to leave active anyway.
Since I exhumed the thread, I wanted to be sure that was clear (for others 5 years from now :)).
