Network Link Down - message 4-5 times per day

The warnings appear on the dashboard as well as in Windows 10 notifications. If I delete them one of the places, they also disappear on the other.
I do not have a network switch.
In windows 10 I can change the setup so notifications from WD app manager does not show in W10. But they still appear on the dashboard.

I have another issue: WD sync says “WDcloud up to date” (No files pending), but there are plenty of files that are not synced.
Are these problems related?
