Have you double-clicked Start.BAT that should be in the folder where everything was unzipped to?
That should set everything up apart from starting the 24/7 logging that has to be set up for each Windows system.
The instructions aren't really necessary until starting Task Scheduler via START_LOGGING_24-7.BAT & even then it should be self-explanatory.
Once set up double-click TestStats2.BAT for current stats graphs & assuming 24/7 logging has started, double-click graphpd.BAT for the graphs.
You can just run TestStats.BAT on its own, but the 24/7 logging tells us a lot more about general & ongoing conditions.
There aren't really any other programs out there for FTTC/VDSL2 connections yet.
Any specific queries, just ask here.
