Thanks for sending the file Todd. I replied here rather than email just to get others thoughts. One thing I noticed is the Fios is on port 2 in all 3 bases. If I have multiple bases in a house, I typically will place them on different ports on each base. It shouldn't be necessary, but I recall way back being told this is best practice. I don't recall if it was in training or just something I heard along the way. It's one thing to try at least. I would probably change the RFID from the 0(letter) ID to just a number on the MRX2 just to see if it helps as well.
