The ISP's DHCP service is not working properly. What to do?

Question

DHCP

Good day to all! I connected the router to the modem, tried to set it up, but nothing comes out. Wi-Fi is available, but no internet access. A cable goes from the modem from the LAN port to the WAN port of the router, but it simply does not see the cable, and in the connection status (cable status) it says "The DHCP service of the Internet service provider is not working properly." From what in such cases to do? The cable itself is fixed, crimped correctly, the Internet goes. I checked by connecting the cable not to the router, but directly to the laptop, everything is ok, the Internet is Internet. The WAN port is also working, the LED indicator is on when you plug in the cable. From I provide you with screenshots of the main modem settings:
If anything, I can make more screenshots. Help please, does not want to work, for the third day I understand. :-(
