So, I have an outdated router that has a COAX cable connected to the modem/router. The modem/router is an xfinity 2 in 1 I think. There is a Belkin router hooked up to the modem with a cable. I've had this setup for a few years now and I am wondering if this is more than I need. I get about 90 download and 12 upload with 9 ping. Whenever I connect to the internet, I connect to the router's. Also, Do newer routers use COAX or is this an outdated thing?
