my prior modem be a DOCSIS 1.1 model from linksy which have a web base user interface point out in the ship installation Guide . I would have give this Motorola modem a perfect rating if the ship box also include info on how to access the modem 's user interface via a web browser . fortunately , on the motorola.com site I find a detailed pdf installation Guide with the web interface IP address that make up for the miss info . the web address be -lrb- ... -rrb- some people complain about the heat discharge by the modem but I do not think it be hot enough to cause any problem as long as the modem be keep in a well ventilate space .
