1.7gbps capacity because of the MU-MIMO (Multi User- Multiple Input Multiple Output)is over 10X the capacity vs what you actually have of 16mbps. Or as expressed simply as math the router can handle a max capacity of 17,000 vs 1,600. I am not aware of any commercial ISP's that offer anywhere near that speed 1.7gbps. My ISP claims up to 400mbps yet recent testing shows around 55 uplink and 23 downlink. The routed Micor posted will handle more than you have and should be future proof for your applications.
Also - ROKU smart TV's can be used by Charter/Spectrum in the place of having to pay a monthly fee for a cable box. In 2 years that is $180 for me so that savings will subsidize my next TV purchase.
Have a great week all. Time to help install a new furnace. FUN FUN FUN
