After turning off the router for several hours and turning it on again, everything flew. Also, everything was flying, and right away, when devices were disconnected from LAN ports. An incomprehensible malfunction, apparently some part is heating up and turning everything off, and after a rest it starts working again. Apparently I'm out of luck. The store returned the money, but a lot of time was killed.
