Why is my Wi-Fi slow?

Measure the connection first, then narrow down whether the problem is your broadband line, Wi-Fi coverage, interference or the device itself.

WI-FI TROUBLESHOOTING

A slow Wi-Fi result does not always mean your broadband package is slow.

Wi-Fi performance can change by room, device, router placement and interference. Run the test where the problem happens, then repeat it close to the router. That comparison is often more useful than one headline speed number.

Compare near the router vs the problem room

If the result improves sharply close to the router, the broadband line may be fine and the issue is more likely coverage, walls, interference or mesh placement.

Check whether only one device is slow

If other phones or laptops perform normally in the same place, the slower device may have an older Wi-Fi radio, driver issue, power-saving setting or background traffic.

Pause downloads and cloud backups

Game updates, photo backups, streaming and large file transfers can consume bandwidth and increase latency. Re-test with heavy background traffic paused.

Router position matters

A router hidden in a cabinet, behind a television or at one end of the property can produce weaker coverage. A more open and central position can improve consistency.

Wi-Fi interference can hurt speed

Neighbouring networks, Bluetooth devices and crowded wireless channels can reduce throughput or make latency less stable even when the broadband line is healthy.

Compare Wi-Fi with Ethernet

If Ethernet is fast but Wi-Fi is not, focus on the wireless network. If both are slow, investigate the broadband connection, router load or provider-side issues.
