I have my A/V reciever in the basement with the TV above it in the living room. Never had a problem controling it through the floor till a few weeks ago.
Now all of a sudden the remotes volume control won't work through the floor, (every other command works) but if I go in the basement with them they will control the volume on my Yamaha Rec.
Only thing I can figure is Xfinity did an udate and caused this.
Any help apreciated
