Did you ever get more info back from Support?
In case anyone else finds this thread, things to check and clear up (especially for home agents) would be stuff like the status.mypurecloud.com page for any regional issues, agent being on home Wi-Fi instead of cabled to the router, ISP fluctuations, network Analysis using genesys tools built into the client or supplied by Support, Perfmon data from Windows...a lot of different performance and network possibilities beyond just AWS/Genesys Cloud issues.
