dnsmasq-dhcp em openWRT ignora o endereço IP oferecido (“ID do servidor errado”)

Question

Estou tentando conectar meu dispositivo OpenWRT como um cliente a um roteador via cabo ethernet. Na maioria das redes, o dispositivo funciona corretamente, mas há uma rede que causa o problema. Você sabe o que posso fazer com isso?
