We just moved our router and TiVo with all the messy wiring into a closet. The TV is on a wall on the other side of the closet and the remote worked well through the wall for a while but is now having problems. It's the same problem discussed in this thread from 2013: Remote won't stay in RF mode Has this problem been figured out? It's a VOX remote purchased in February 2018 and the TiVo box is a Roamio Pro. I turned off the TV's WiFi in case it was causing interference but that didn't help.
