:Your signal levels are probably borderline and fluctuating,
leaving little margin for error. Each splitter on the line
between the modem and the tap reduces the signal level by at
least 3.5db.
I feel for the Mediacom employees, hopefully their management
folks will get their ducks in a row and get them what they
need to fix the problems.
Signal levels are not the only thing that can go wrong. They do have capacity issues from time to time, and even more so lately. I'm in Des Moines area as well and just went through a capacity issue requiring node planning. It took quite some time to get accomplished.
