worked right out of box . Make sure to call you cable company and give they the MAC address and the serial number to activate it . then you just hook it up directly to you pc or a wireless router -lrb- which I do -rrb- , and you be good to go . no issue so far -lrb- only about a month into use -rrb- . I pair mine with a Medialink Wireless N Router - 802.11 n router . this unit from Motorola be quite small and very light .
