What is the best way to get an intermittent Internet issues fixed?

I moved into this house last September and have had intermittent issues since moving in.  Speaking with my neighbor, this is apparently normal for this neighborhood.  When I contact COX support via chat or phone, the usual process is to reset my router and modem which does nothing. Then at a later point in the day everything clears up.  When the agent can't fix the issue they schedule a technician but by the time the technician comes out everything is working. Is there a way to have something set up so that when we get the dropped internet we can inform them or have a monitor placed on the line to see the drops in signal to alert the technician?
