Poor audio and visuals fading out before a meeting concludes.

I've had some very poor quality experiences, especially in the last 2/3 months where my audio seems to fade off and, once in a while, the visual images become very slurred and impossible to understand. I've had my Chrome book checked out and that's not the problem and the computer hook-up for the house seems OK. No one else is having these problems anyhow.  So can Zoom help me or--I don't know, what should I do.  Unreliable Zoom may be worse than no Zoom at all.
