Intermittent 100% packet loss

[rbw747]

We use JK 3 or 4 times a week and this problem is happening muliple times in every session. Everything is working fine then the audio path between 2 people starts cutting out.  The internet packet loss shows 100% for both people but it only last a couple of seconds then it's fine. But once it starts, that connection will keep cutting in and out. Nobody else in the session is effected. Re-syncing, re-entering the session does not fix it, we have to start a new session and have everybody rejoin. This will usually work for awhile and then the problem reappears, sometimes between the same two people but sometimes between 2 different people.

We are typically all local with good gear and hi speed fibre internet and have no latency issues. It happens between Windows clients and between Windows and Macs.

Any ideas??? Thanks.
