I buy the Cisco-Linksys cm100 cable modem to save rent it from Comcast . should have do this year ago . I must have spend enought on rent to buy 3 of they , but Comcast would not just let I have it . it arrive in a few day , be easy to setup -lrb- although you have to call you cable provider and they do something on they end -rrb- and my cable bill go down $ 5 a month .
