BRICK ROUTER / router

Block router added and stacked according to necessity.We can have fun of stacking blocks and can add as many ports as
we want by using the principle of
LEGO blocks familiar to us.
a new router should be bought,
but it is difficult to buy a router with wanted number of ports.This can increase the number of ports without any restriction,
and makes it possible to overcome the limitations of ports, which a router has.
