We need to see the Host log to see what might be causing the issue. Note that whatever the problem with connectivity the Host log should reflect that. That's why this is essentially the only and final source of any information regarding connectivity problems.
You have also updated Viewer and Hosts to version 126.96.36.199, correct?
Yes, absolutely. Note that you may not notice such small breaks when you use a web browser because a web browser essentially just downloads a web page onto your computer and then you view this page offline (perhaps this explanation is simplified a bit but still applies to modern browsers).
Things are different with remote controls though. They need a relatively stable connection to "stream" remote image and keep the connection alive. The fact that some competitor products may seem "more stable" doesn't mean they are. It only means that they found a way to trick you into believing that what you are seeing on your screen is a real time image (whereas there might be a complex algorithm in effect to "smooth out" little network disturbances).
