STBA-3802 Random Channels dropping out for 20 minutes or so Time Warner TV

This question is about «STBA-3802 Random Channels dropping out for 20 minutes or so», with Time Warner Cable TV and apps. The following is a common occurrence for me and my Spectrun Cable TV and I am wondering f anyone else experiences this and has a solution After surfing some & seeing vantage fx review what is on, I’ll often settle in and watch 2 channels by switching back and forth when one goes to commercial. I first get the ‘One Moment Please Your Channel will start shortly» on screen, followed by the «Channel Unavailable — we are sorry we’re unable to tune to this channel.
