    <font face="Tahoma">Hi all.<br>
      <br>
      So I may have fixed this for my end, and hopefully others may be
      able to use the same fix.<br>
      <br>
      After a tip from Karl Auerbach and this link:<br>
      <br>
          <a class="moz-txt-link-freetext" href="https://developer.apple.com/forums/thread/97805">https://developer.apple.com/forums/thread/97805</a><br>
      <br>
      ... I was able to fix the problem by disabling Bluetooth. <br>
      <br>
      However, disabling Bluetooth was not enough. I also had to disable
      all Location Services.<br>
      <br>
      After that, I re-enabled Location Services and only allowed for
      two features:<br>
      <br>
          - NetSpot<br>
          - Find My Mac<br>
      <br>
      With just those two location services, as well as Bluetooth
      disabled, I have no more high jitter.<br>
      <br>
      App performance like Zoom and Youtube uploads are now crisp, with
      0.0% packet loss.<br>
      <br>
      So looks like that Bluetooth is a huge problem. Confirmed by
      opening the "Console" app, and adding "scan" in the filter bar,
      top right.<br>

      A peak latency of 13.5ms after 300 packets:<br>
