I order this to replace my Comcast xfinity modem that I have be rent every month . when it arrive I simply contact Comcast and provide the number on the modem to have they connect it to the internet . this save I $ 8 a month now and pay for itself . the internet also seem it I be quicker and I rarely have to reset the modem , unlike the Comcast one . I have have this modem for a few month now .
