The package speed is delivered to the router; a wireless device’s result also depends on its radio, band, signal, interference, mesh hop and current traffic. Test the gateway or a capable wired device first.
They may use different servers, routes, test durations, browser limits and load. Use the ISP/router test for line-to-router speed and a reputable nearby server for device speed.
Pause large downloads, turn off VPN, use one modern device near the main router, confirm the band, and repeat three times. Also run a gateway or Ethernet test.
A 100 Mbps Ethernet negotiation commonly produces results near 90–95 Mbps. Check for a damaged/two-pair cable, 100 Mbps port, adapter/dock limit or forced speed setting.
Upload can be consumed by cloud backup, cameras, video calls or malware; Wi‑Fi interference can also affect both directions differently. Test wired with background uploads paused.
More household traffic and neighbouring channel use can raise contention; an ISP network issue is also possible. Compare gateway and client tests at matched times.
The broadband upgrade does not upgrade the laptop’s Wi‑Fi radio. An older 802.11n/one-stream client, driver or 2.4 GHz connection may be the limit.
Idle devices use little internet capacity, but active or chatty devices share airtime and bandwidth. Cameras, backups and streams matter more than the raw device count.
The router test measures internet delivery to the gateway; the phone test includes the Wi‑Fi path, phone capability and location.
Throughput and delay are different. Congestion, bufferbloat, weak signal, retries, VPN routing or game-server distance can raise ping without reducing a headline speed result.
