We have Spectrum and use a dual band modem/router combo we purchased ourselves. Our service is 200Mbs and we use mostly the 5g band. We have a smart TV, AppleTV, two iPads, two iPhones, a desktop, and 4 Reolink WiFi cameras all on it. We have no speed issues with any of it. Of course, we are not using all of them at the same time, but the cameras are always on and when we watch TV we mostly use AppleTV and are messing around on our iPads at the same time. I think all of the other ISPs offer at least 100Mbs as their basic plan. With the way most of use the internet today, and the devices we have, you would want 100Mbs minimum.
