random disconnects

Hi everyone.
I've been having these short random disconnects.
In cmd it looks like this

Then everything works again.
And it goes like this for some time with the same intervals like every 30-40 seconds. Then stops.
There's a router, two pc and console, all connected via lan and lots of wifi devices. Everything works great except one pc that has those random disconnect issue.
router: asus rt-ax86u
oc: windows 10
mb: asus dark hero with Intel WGI211AT and Realtek RTL8125CG. Tried both of them, but have that problem on each one.
Any thoughts?

Have you tried a different cable or port on the router/switch?

Yes. I also had that problem with the previous router too.

Are you able to put your PC directly onto the modem, bypassing the router, to test it?

Yeah. But is there a point in checking if the problem is on only one device?

It would tell you if it's the modem or the router. Obviously if it works OK, then the problem lay in the router for sure.

Precisely, or something screwy on the motherboard or OS install.

Does it happen over WiFi [if your board offers that as well]?
