Provider Drive-Toretsk

Ps I have a router that is connected to the main router = configure again - no

Another merkus router is connected to the main router via wire

Answer 1

I'll try to guess
the home Internet with a "gray" address? Or "white"?
What address does the router get? (You can see it in the router settings in the "status" tab. What IP do you see when you enter a site , for example
, yoip.ru, 2ip.ru, speedtest.net? Do
these IP addresses match? by MAC address, so changing it is not an option

Answer 2

Can you formulate thoughts? nothing is clear. neither the network scheme, nor which specific IP needs to be changed.
Why did you decide that the IP should change after the restart?
