excellent way to get around the $ 7\/month charge that Comcast require for they dated cable modem . as other have point out , you do not need to call Comcast to set this up . you only need you account number and the contact phone number that Comcast have on file for you . setup and installation for Comcast be as follow : -lrb- 1 -rrb- turn on the modem and connect it to you cable connection . do not plug in you computer yet -lrb- 2 -rrb- wait a few minute for the blinking to stop . -lrb- 3 -rrb- plug in to you pc and turn it on . -lrb- 4 -rrb- you should be automatically redirect to the Comcast self activation page . type in you account # and phone # -lrb- 5 -rrb- go to a comcast customer service area to drop off you old modem -lrb- and save on return shipping -rrb- except for step 5 , the whole thing take I 15 minute . my speed have go from 14 - -rrb- 27 mb\/sec download . actual speed have go from a peek of 1.8 mb\/sec to 2.8 mb\/sec . not bad , and you save money in the long term
