I had two incidents over the weekend. The first time, I lost connectivity to the Rev E but then soon discovered that I had lost all Internet. I checked the FIOS box at my house entrance and had a red flashing MoCA light. I waited a while and then the problem corrected itself and my Internet service returned.
The second incident I lost Internet connectivity just to the Rev E. I double checked that I still had it everywhere else though the Rev I. I had to cycle power on the Rev E and then reconnect my devices to the Rev E.
No further incidents in the last 24 hours.
