I have been experiencing outages in my FiOS Internet access since install. The interesting thing about the outages, is that they occur more or less daily at the same time of day (Approximately 8PM local in N. Virginia.)
I contacted support shortly after the initial install and was sent a new modem. That didn't resolve the issue and I was sent another new modem and power cable. Although this second new modem didn't resolve the issue, I became frustrated with the phone trees and holding, so I decided that calling in for support wasn't worth my time.
Recently the outages have become more frequent, so I decided to take up the cause again and call the trouble in. I now have an appointment for a technician to check out my ONT this weekend. I'll keep this post updated with my progress.
For reference I am running:
Model - MI424WR-GEN3I
