If what has regularly happened in your home was explained in full to your electrician, he should have been able to suggest a whole home solution. I know high school installers who know that much. This goes beyond 'we all come from diverse backgrounds', which I grasp. We are talking electrician's mental toolkit 101 here.
Oh, and my portfolio was well protected before the crash, btw, if you really must know. My friend can trade over his ATT wireless LTE cellular data connection, FWIW. The lag time actually is decent enough for that purpose in a pinch. You might want to look into it as a backup.
