I too have had problems with the Intel upgrade driver.
I removed the current dated driver and reinstalled an older one that worked V 15.3.1 and reestablished the connection with the Netgear PTV3000.
It was working fine, then a Windows Upgrade downloaded with a new version and communication failed.
Rolled back the driver to V 15.3.1. and it worked again!
Something is really amiss with the new driver.
Do not use automatic upgrades until Intel figures out what they did wrong between versions.
