Zoom Crashing Network on MacBook Pro

I'm having trouble with Zoom Meetings on my new MacBook Pro (running Catalina 10.15.6). I'm the host of a Zoom meeting with 26 participants. Without fail, about 5 minutes into each meeting - my entire network shuts off. I'm hard-wiring in with an ethernet cable, and usually experience no trouble. When the network shuts off, I can't access the LAN line or Wifi until I restart the computer. Has anyone else had this issue or know a work-around? (I have a back up PC running in the meeting and that keeps its connection consistently). I've been in touch with my Internet service provider, and all seems good there. I'm running the latest update of Zoom too. Could it all be a bandwidth issue that goes back to my Internet Service provider? Or is it something to do with Zoom and the computer?

MacBook Pro 13″, macOS 10.13

I've got a Satechi USB hub (Thunderbolt 3 port) with ethernet cable attached to my MacBook Pro 2020 (Big Sur). It will work all day long providing stable internet, but reacts the same way with Zoom. Complete failure, and all internet connection shuts down, while we have extensively troubleshooted tracking the IP address: everything looks fine. This happened three times to me today already.

I know this is an old post, but I do have one possible tip: unplugging the Satechi hub from the port keeps me from having to restart my computer. Then wi-fi picks up and Zoom continues.

(None of this ever occurred with my 2013 MacBook Pro. Absolutely 100% reliable with ethernet cable connection.)

MacBook Air, 2020, 13; MacOS Catalina (10.15.7); using a vmade 10-in-1 USB C hub to allow ethernet (Cat7) to Sagemcom Fast 5364 wifi router.

If I use the ethernet I get disconnected after c.10 minutes on Zoom; Teams; or Blackboard Collaborate Ultra. I cannot switch to wifi, or tether to 4G, until I've restarted my Air.

This is killing me - it's my work and I can't keep using up data on my phone. It's not a broadband problem; it's not a 'zoom' problem - it's something to do with ethernet/usb-c and all conferencing/video-call services. I've found threads on Windows reproducing the same problem - it's ethernet/usb-c: anyone found a fix?

As you mentioned, this seems to be an issue related to ethernet adapters (realtek) triggered when using web conferencing apps (Zoom, Teams). I've seen it happen on a current Dell XPS running Windows 10 and the current Intel MacBook Pro running catalina.

So far the only workarounds have been to use wifi instead, and if that's not possible, try a different usb-c to ethernet adapter (if you can find a non-realtek one). It appears realtek is aware of the issue, but no (software/driver) fix yet...

Same thing I have found. Ethernet fails after a while 1 hr or 2+ subsequent zoom sessions. I have no issues on wi-fi

Doesn’t happen on Teams so I think it’s on the zoom side.

EXACTLY the same issue 2 months later. At a loss here.

Same issue happens on Teams - PC or MAC. Might be hub compatibility. Anybody found a dock (with Ethernet port) working with M1 MBA/MB?
