Loss of contract during a meeting

[TonyFinch]

Hello.  I join 2 regular quarterly Zoom meetings.  The 1st is from 10am to 11am followed by the 2nd from 11am to 12noon (separate links to join each meeting).  Part way through the 2nd meeting (11am to 12noon) I always lose contact.  All the other participants remain connected to the meeting.  It takes time to join again and I've missed part of the discussion.  Can anyone help me determine the cause of such a drop in connection and how to fix it?
