Why am I not getting the full package speed over Wi‑Fi?
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.
SpeedWhy do different speed-test websites give different answers?
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.
SpeedHow should I run a fair Wi‑Fi speed test?
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.
SpeedWhy is my gigabit Ethernet test stuck around 90 Mbps?
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.
SpeedWhy is upload slow but download is fine?
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.
SpeedWhy is Wi‑Fi slower in the evening?
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.
SpeedWhy did my old laptop get slower after I upgraded broadband?
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.
SpeedDoes having lots of devices slow the Wi‑Fi down?
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.
SpeedWhy is the router app speed good but my phone speed bad?
The router test measures internet delivery to the gateway; the phone test includes the Wi‑Fi path, phone capability and location.
SpeedWhy is latency high even when the speed looks fast?
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.
