Estou tentando conectar meu laptop a um Raspberry Pi3, a ativação da conexão falha. O log do sistema no laptop mostra um tempo limite do cliente dhcp.
O tempo limite em /etc/dhcp/dhclient.conf está definido para 300, mas parece que ele falha antes disso.
A conexão de outros dispositivos para o mesmo RPI e do meu PC funciona perfeitamente.
Por favor, sugira como diagnosticar ou resolver o problema. Aqui está o log:
