Unstable Internet Connection - Wired Connection Fast Internet

[BITS]

I'm getting lag every 2-3 minutes for about 15-20 seconds.

I'm on a Desktop PC which is powerful.

I'm not on Wifi, I'm directly attached to the network.

Speedtests are all super fast (gigabit ethernet, fast upload and download, latency is low teens)

I use the desktop app not through the browser.

All other services seem fast - Teams, Gotomeeting, VoIP phone, Discord all work no problems.

I'd like to try some more advanced troubleshooting (I own an IT Services business)

Are there any servers I could tracert to and test the connection over several minutes for packet loss along the route?

Have you discovered the Zoom Settings “Statistics” tab?  There’s a lot of good information on there.

Also monitor Task Manager and Resource Manager to see if there is some blocking service or system process.
