Hello luuiz, welcome to the community!
I assume that you “cannot” find your Shake into your LAN. From the pictures that you have sent I can see the blue and red LEDs seem to be working as they should. Are the green and orange LEDs attached to the LAN port (circled in the picture) are also active?
You can also try to use an app like Fing, as explained here: Please read before posting! to see if manages to find the Shake in your network.
