Ziggo network engineer has replaced tv cable, noise is now gone.
Shaky image on one tv channel remains but this is a problem somewhere else.
Have not yet tested getting into cable modem or testing speed.
Speed is something like 90 Megabits down, 10 Megabits up or something.
But I take this with a grain of salt, might be a bit higher than previously though
Bye,
Skybuck.
