Enjoy rapid Internet connectivity with this ARRIS SURFboard SBG6900-AC cable modem and Wi-Fi router, which feature download speeds up to 686 Mbps and Wireless-AC technology with Wi-Fi speeds up to 1900 Mbps.
Q: Is this compatible with Optimum... and, is this a modem and router in one unit?
A: I am not famkliar with Optimim but it seems to be TV over Wi Fi. If what you want is IPTV, then any internet service you hire from a major provider (like Comcast), should give you access. The Arris Surfboard 6900 is a cable modem and a router in one box. It works great. You can use it with Comcast. You can service any Wi Fi capable equipment, but the speed you buy will be crucial. The more, the better.
Q: Will this work with Comcast/Xfinity?
A: Yes, that is what I bought it for :)
Q: Can I use this equipment for my Verizon fios in new jersey. For internet?
A: Yes you can. I did it with mine
Q: I need a phone connection router
A: This one doesn't have phone support as you likely figured out. Try the Netgear model if you are an Xfinity customer.. Not cheap, but reportedly good. I've had good luck with mine since I installed it. https://www.bestbuy.com/site/netgear-nighthawk-dual-band-ac1900-router-with-docsis-3-0-cable-modem-black/5787800.p?skuId=5787800
