FAQ
How much speed does a household really need?
Add the demand of simultaneous activities, not the people. One 4K stream (25 Mbps), a Zoom call (3), a gamer (4), and browsing (2) sum to about 34 Mbps — the busy evening hour is what your plan must survive.
Why does 100 Mbps WiFi feel slower?
WiFi typically delivers 50–70% of the wired plan speed after distance, walls, and interference. A 100 Mbps plan may give you 60 effective Mbps — enough for most homes, but the calculator shows your true margin.
Do smart home devices matter?
Individually, barely — an idle speaker sips 0.1 Mbps. Twenty devices still under 2 Mbps combined. Their real cost is router airtime when many respond at once, which shows up as latency spikes, not throughput loss.
