Hi @sandert 

Thanks for posting in our business forum.

Based on the log, it looks like a network fluctuation. As you can see it does not always disconnect but during scattered time. And suddenly populated at the same time.

You might wanna review this with your ISP.

If you believe it is a problem with the router, you can consider RMA.

I don't think it is a problem because if you have examined the physical wires and cables, nothing changed or touched recently and it suddenly behaves like this, it is likely to be the ISP or the modem/fiber. It is also not a problem with the hardware as far as I think.

RMA is the easiest way to rule out the problems on the router. For me, it has nothing to do with the router.
