nighthawk x6 question
I currently have a suddenlink wireless modem. I wanted to replace the rented modem for something that would also support 3 smart tvs, 4 smart phones, 2 gaming systems, etc. I was told that this nighthawk x6 would replace the modem and have enough power to support everything. As I am getting ready to install it, I realize that I still need the rented modem. Is there another alternative to purchase something that will support all of the devices, or will I need to purchase a modem plus this router?
