The access point isn't functioning with both wired and wireless connections.

I paired them correctly, ensuring identical sequences. Should I have turned off DHCP on the second router?
Many current gadgets switch automatically, so ensure the cable is correctly aligned (same wire sequence on both sides) or properly arranged (crossover setup). Each pair should be flipped, using T-568-A on one end and T-568-B on the other—not just a simple swap. @bcguru9384 proposed an alternative approach that avoids turning the second router into an access point, which is typically the better choice. The referenced article aligns closely with what I previously recommended. Since you followed that guidance, it’s likely there’s an issue with this specific device. Could you confirm its model? Try updating or re-flashing the firmware to check for any errors. I’ve noticed problems that a successful re-flash can fix. To update, simply upgrade to the same version already installed. What model was this router? If the update didn’t work, it might indicate a connection drop during the process or hardware damage, making it unreliable for regular use.
Router makers could guarantee that local DNSServer is configured with at least one DNS address—ideally the router's gateway—to operate in both primary and WAN lookup modes. Both WAN and local name resolution should be supported, leveraging the list of connected devices. On Windows Server, use netsh dnsserver set set mode=both with a matching DNS address. For consumer OS, install or import the DNSServer tool via Add Components, though this isn't available in router firmware (it's Linux-based). If you enable RIPv2 between routers, NAT issues should resolve as clients share client tables thanks to MDSOS. Rip route data works too—UPnP relies on it, so disabling it might explain UPnP's sensitivity.
Thank you for your responses. I decided to purchase a wireless repeater and convert it into a wired access point, which eliminated the hassle and provided a cost-effective solution.
