I am just not convinced that will solve this issue but worth a try. Has Ceton ever seen/heard of other Verizon FIOS users suffering the same. There was a report here of content flag changes during this preview,
Could this be root cause?
I recently moved and got FIOS here. The installer didn't think I would need the low-pass filter, and I went in the channel map to find the higher frequency channels I thought it might interfere with and it didn't. Turned out that was wrong though.
The default configuration of the Actiontec router is 1GHz MOCA for the connection to the ONT, 1150MHz for the LAN (to talk to set top boxes or bridges). You would think if there was going to be interference it would be from the 1GHz channel. As far as I can tell that was fine. However, with the LAN MOCA enabled in order to use a MOCA bridge upstairs, I got interference with QAMs 49-51 (375-387Mhz), 1/3 of the MOCA frequency, so its some kind of harmonic issue which the filter blocks. I think FIOS is actually sending the same signal everywhere (why else do we have so many QAMs wasted on Pacific time zone channels?), which means if you have this you will have problems with Travel HD, Lifetime HD, FX HD, Fox Business HD, Fox News HD, and EPIX HD. It wasn't breaking other channels for me, but apparently was making them tune slower -- switching channels is about 3x faster with the filter installed!
If you are able to do without MOCA, make sure you disable it for BOTH the LAN and have the internet connection switched to ethernet. (or just disconnect the coax from the Actiontec).
