Step by step

  1. 2 min

    Measure signal strength at the source

    Stand directly next to your wireless router and run a speed test using a reliable service. Note these results as your baseline maximum speed. Compare this figure against the speeds you currently receive in the problematic area.

    Note: A significant drop near the router suggests a modem or ISP issue rather than a range issue.

    Perform a signal survey with a Wi-Fi analyzer

    Install a Wi-Fi analyzer application on your smartphone and walk toward the dead zone. Monitor the RSSI (Received Signal Strength Indicator) levels; a signal weaker than -70 dBm is likely the cause of your connectivity drops. If the signal is non-existent, an extender has no source to repeat.

    Note: Stay within the range where your phone still detects a signal, even if it is weak, for an extender to function.

    Check for physical obstructions

    Identify large metal objects, thick concrete walls, or mirrors located between your router and the dead zone. Wi-Fi signals reflect off metal and are absorbed by masonry. If physical barriers are present, an extender may fail to pick up a viable signal to repeat.

    Note: Relocate your existing router to a more central, elevated location before purchasing additional equipment.

    Review the connection type

    Determine if your devices use the 2.4GHz or 5GHz band. While 5GHz provides higher speeds, it has shorter range and worse penetration through walls than 2.4GHz. If your devices constantly switch bands, an extender with band-steering capabilities is necessary.

    Decide between an extender and a mesh system

    If you require consistent coverage throughout a large home with multiple users, a dedicated Mesh Wi-Fi system is superior to a standalone extender. Extenders often create a separate network name (SSID), causing devices to disconnect when moving between zones. Purchase an extender only if the problem is confined to a single, small, isolated room.

    Note: Mesh systems manage handoffs between nodes seamlessly without manual intervention.
