I have have this rmodem for about 6 month now and I be very happy with it . it be literally a plug and play with my Comcast internet . I be able to plug the modem in , follow the step in my browser and I be up and run . you 'll just need to have you Comcast info handy when you set up this -lrb- or any other -rrb- modem . not have to call tech support and relay they the serial number , ect ect be a big plus . also , the lack of the $ 7 a month modem fee be nice as well . in a few more month , this modem will start pay for itself . one slight oddity I notice vs the older surfboard modem : no more blinking light to denote traffic . all the light be solid . you will get a blinking orange light if you have DOCSIS 3.0 available in you area . that be not relate to any internet traffic ; it just blink on its own . all in all , very happy . Easy to setup , solid performance . I have not have to do a thing since I plug it in back in February .
