I'm looking for the best modem and router for a 150 sq ft room to stream on my LG OLED TV which I'll hardwire, with my only other devices, a Galaxy S7 phone + eventual Soundbar or Home Theater equipment. I'll be using Comcast Xfinity Performance Pro Internet Service and while I've considered purchasing a Gateway combo - which should be sufficient - have heard that it's far better to use a separate modem and router. Still, I wonder for a room this size. whether the difference would be that significant. Any thoughts?
