If you have a phone line on your internet don't buy a wireless modem from the list that on comcast list site.Not even from Amazom.I did and has to send 2 modem back to Amazon.Because when you call Comcast they will say it will not work with the phoneComcast lie to me I ask and they said Arris Motorla woll work. After I get it and call them they said it doesnt work with the phone. I will have to go to comcast and buy or rent a upgrade wifi modem with the phone. So I have to go to comcast to get a new wifi modem . the tec said to take the old modem with me when I go to get the new modem.But I not going to take my old modemback to comcast until I get the new one working.
