is the metal connector(filter?) thing inside the vm box needed? is this built into the quick start cable?
ive moved into a house that just has a cable and little end convertor (quick start cable pushes on).
my services are working but some downstream stats seem to be going high above 10's.
Are you referring to an isolator (which would be fitted into the old wall boxes) or an attenuator (the add-on inline part to reduce signal levels)?
Old wall boxes had a metal isolator box fitted into them. I believe the new connection cables have the isolator already joined into the cable (a visible larger section part way along the cable). Your downstream levels look like they are near (or at) VM's upper limit (+10db ?)
