Delayed and erratic response to X1 remote

I have been experiencing delayed and erratic responses between my remote and X1 box.  The problems are 1) Press a remote button and nothing happens,  2) Press a remote button and something totally different than what was requested happens,  3) Occasionally a message saying that I have a bad connection to the internet will pop up on the screen.  This message seems a bit strange to me since this is a Cable connection to the X1 box and not an Internet connection.  There have been other issues, but these are the most prevalent.  What's up here?  Should I just take the box and the remote in and swap them out?  Or is there some other solution to this?
