My internet connection keeps dropping intermittently, sometimes for 30 seconds sometimes for as many as 5 minutes. It always comes back by itself but the outages obviously interfere with Zoom calls and such. In the network logs I can see many critical events:

I've tried all the usual resolution techniques (restart the router, check cables are tight, etc) and none of them resolve the issue. Other similar forum posts suggest that an engineer visit is required to identify the issue. Any other suggestions or do I need to wait for someone from VM to book an engineer?
