Network Connection drops and reconnects in Guest OS

I'm using Ubuntu 22.04 and VMware WS pro 16. In the guest OSes, I have frequent network disconnects, which are extremely annoying when you have e.g. a video conference. Also when I'm working with Office 365 in an Office program, I frequently get the message "No Internet, check your connection" and the cursor freezes and I have to wait a moment until the Internet connection is back. This happens on both Linux and Windows guests. It does not seem to happen on the host.
I have checked the logs of a Linux guest, it says the following in regular intervals:

I am using NAT for the guests.

Any ideas are highly appreciated.
