really not much to say , hook it up to the cable and the router , plug it in , give my cable company the MAC address and everything work as advertise . buy this to replace my ancient Motorola sb5100 that be still work perfectly but the cable company encourage everyone to switch to DOCSIS 3.0 to take advantage of future speed increase . completely seamless transition from the old hardware , no problem with NAT , etc. . pro : idiot-proof set-up and hopefully -lrb- if like my old one -rrb- rock solid reliability . con : none that I can think of .
