Hi, thanks for sticking with this... Yes, I am still using a Telus WiFi Hub, just like the the OP... which got me thinking that we might have the same issue.
Have sent him a PM, but no reply. Sending you a PM as well.
Back to troubleshooting..
I can run Zoom on a laptop or a tablet, using the same hub without problems, so it is specific to my Win 10 PC.
In the procmon traces, I can see a definite 4000 ms window every 60 seconds.
Starting with:
Date & Time: 2021-06-13 9:13:38 AM
Event Class: File System
Operation: DeviceIoControl
Result: NO MORE MATCHES
Path: \Device\Mup
TID: 11552
Duration: 0.0000123
Control: 0x1403a4 (Device:0x14 Function:233 Method: 0)
And ending with:
Date & Time: 2021-06-13 9:13:42 AM
Event Class: File System
Operation: DeviceIoControl
Result: NO MORE MATCHES
Path: \Device\Mup
TID: 11552
Duration: 0.0000226
Control: 0x1403a4 (Device:0x14 Function:233 Method: 0)
There is an exact timing sequence here... 4000 ms - every 60 sec
Wonder what is triggering this..
