Hello everyone, and thank you in advance for your help.
I’ve been using a QNAP NAS (TS-253BE-4G) for years, which was set up by a friend at some point. I haven’t really paid much attention to it, but I want to change that this summer since I need a bit more backup security. But that’s just a side note.
Every night at 2:00 am (I guess that’s how it’s set up), I get notifications about the status of my NAS. That’s all fine.
However, since yesterday evening, I’m getting several notifications every half hour with the following content:
NAS Notification
Severity: Warning
Date/Time: 2026/04/20 09:30:34
App Name: Network & Virtual Switch
Category: Infrastructure
Message: [Network & Virtual Switch] Interface “Adapter 2” disconnected.
and/or:
Severity: Info
Date/Time: 2026/04/20 09:30:52
App Name: Network & Virtual Switch
Category: Infrastructure
Message: [Network & Virtual Switch] Interface “Adapter 2” connected.
It keeps switching back and forth like this.
What could be causing this? Is there something I need to check, and if so, what?
If anyone could help me out or provide some info, I’d really appreciate it.
Best regards,
André
