Download stops when a device on USB Ethernet adapter is powered off

When downloading a file from the internet via an Ethernet connection on the computer’s motherboard, Brave stops the download - with no error message - when I turn off an audio interface connected to a separate Ethernet port on a USB Ethernet adapter.

Details:

Brave is running on a hackintosh with Monterey 12.3.1 connected to the internet via an Ethernet port on the motherboard.

I have an audio interface connected via Ethernet to a USB-C to Ethernet adapter.

When I turn the audio interface off, the download stops. Brave lets me re-start it, but this is annoying!

If I recall correctly, the interruption also happens if I start with the interface off and turn it on during the download.

This problem does NOT happen in Safari 15.4. I can turn the audio interface off and on during a download without incident.

macOS 12.3.1 Monterey
Brave 1.37.109

Intel i9-9900k, Open Core 0.7.9 (iMac 18,3)
