At present I use a separate modem w my 2.4 ghz Netgear router for use w Comcast cable. Need advice on what I need. Should I get a combo modem & router? Don’t I want a 5.0 ghz only? What do the figures 24x8, or 8x4 mean? Why DOCISS 3.0 or 3.1? I live in a small home, just me, I like streaming Comcast on my iPad Pro (10.5”) in bed. I don’t have a gaming console, YET, but maybe, as the Mac is becoming useless for gaming on Steam. Why do combo cable modem routers vary as much as double in price? What is inside that doubles the price? Here’s the thing, I stream (2.4 ghz) Comcast movies fine now on my iPad Pro (10.5”), but isn’t the 2.4 band crowded in my neighborhood?
