I've complained to chess.com several times and I'm still loosing connection about 1 in every 4 games. It takes all the fun out of playing on this site. My internet connection is apparently fine, in particuar I play on Lichess all the time with no problems whatsoever. I've tried several browsers and use both Linux and Windows, so I doubt this is a problem specific to my set up.
There's are multiple things that can cause issues.
There are some things that you can do to minimize connection issues. Though if the problem is between you and the site then they may not help
