Slow Wi-Fi? Try the two-device test

Before buying a new router, compare your phone and computer in two places. The result helps narrow down the cause.

If a video call drops in the bedroom but works in the living room, you already have a clue. Compare your phone and computer in the same conditions, using the same test service at a time when the problem usually happens.

Run two tests

  1. Start next to the router. Connect both devices to the same Wi-Fi network. Temporarily turn off mobile data on the phone so it cannot switch networks. Pause large downloads and run the speed test on each device in turn.
  2. Repeat where the connection struggles. Note the room, time and results. If video calls are the problem, look at the upload figure too. If it only happens in the evening, try the same test during the day for comparison.

What do the results mean?

  • Both work next to the router and struggle in another room. Coverage is a likely cause. Try moving the router out of a cupboard or putting it higher up, then repeat the test before buying anything.
  • Only one device is slow. Try it on another Wi-Fi network. If the same thing happens there, start by checking that device.
  • Both are slow next to the router. If you can, connect a computer directly to the router with a network cable and test again. If the wired result is poor too, share the measurements with your internet provider.

If speed tests look normal but one app keeps dropping out, check whether other websites load on the same device during the interruption. Write down the app and the time. That is more useful for troubleshooting than a single speed reading.
