See how speed, latency, and coverage problems show up in real homes.
Use practical visuals to connect the concept to your own setup.

Connected home internet devices illustration — Start with the full home network, then narrow down the weak link.

The network chain

Think in layers: provider connection, termination device, router, local Ethernet or Wi-Fi, and the client device. Performance is limited by the weakest relevant link.

Speed versus responsiveness

Throughput measures how much data moves over time. Latency measures delay. A fast plan can still feel poor if latency spikes under load.

Ethernet still matters

Wired connections remain a useful benchmark because they remove radio interference and coverage from the test.
