Video conferencing

For the last 3-4 months (mid-November) I have been experiencing intermittent connection issues while on video conference calls.  This occurs regardless of video conferencing platform (Google, Zoom, Teams, etc) and occurs with multiple computers both connected via wifi and LAN, never with a VPN enabled.  Speed tests show the connection is performing as it should overall but the video conference calls freeze for 1-3 seconds at a time and no internet connection is available during those instances.
