I installed three EERO Pro in a house a few years ago and that Winter, I noticed the network was offline. When I spoke with the homeowner, he said they were removed and replaced by Orbi or something that didn't work very well, on the advice of the Time Warner cable guy. They were far worse and there was absolutely no problem with the EERO, the problem was in the cable from the curb to the house.
My mechanic told me, "I couldn't repair your brakes, so I made your horn louder."
