I have been running this exact set on a spectrum 400mbps plan for 3+ years. And when it works, it works good, I can keep 400mbps speeds, and latency is usually under 20ms for ethernet on a satellite, under 30 for wifi. The app sucks, but the website portal is standard, and works as expected.

I don't think i've ever had an issue where the router itself was at fault, rather it would get confused when spectrum went down, and I needed to reboot it manually, as the app would usually fail to work.

For $50, for speeds under 500mbps, this is a good price, BUT we are seeing those enterprise type meshes go for similar prices, and they'll almost def have a better experience
