I have Xfinity Triple Play and ended up buying the Xfinity Arris integrated modem/router because it was only one with an RJ11 phone jack and I wanted to stop paying Comcast $10/month to "rent" theirs, I wanted to buy Netgear AC1750 but that doesn't have RJ11 jack.I Installed the Arris modem/router but performance is lousy. Is there any way to still get Triple Play (phone/tv/internet) without having to use Xfinity/Arris modem/router, like using the AC1750 with some kind of VOIP modem?
