My router's IP address is I tried to access it but without success, because my WIFI address is and my Ethernet address (via the Thunderbolt port) is

How can I configure my router without having internal IP addresses?

How do you know your router's IP address if you can't connect to it? – patrix Jul 10 '12 at 12:17
Because I once configured it so on a Windows PC. – doonot Jul 10 '12 at 12:18
Where does your Mac get the IP address from? If the router acts as a DNS server the Mac should pick up a "proper" address automatically. – patrix Jul 10 '12 at 12:20

Settings - Network - Thunderbold Ethernet - Configure IPv4: Manually: After this I am able to access the router.

Alternatively, you could have changed the service order to place the Wi-Fi connection (which looks like it would have worked) above the self-assigned address. This sort of thing usually is a temporary issue unless your router has access controls based on MAC addresses which would explain why it wouldn't issue an IP address to a new network endpoint. – bmike Jul 10 '12 at 13:05
