Wi-Fi extenders: choose one for the gap you actually have

Start with the shape of the decision

An extender can help one local coverage gap only when it receives a usable signal itself. Measure the gap and identify a healthy relay point before comparing specifications; an extender placed inside the dead zone simply repeats a weak connection.

Free checks first

1. Move the router into the open, then retest the problem room on both supported Wi-Fi bands.
2. Test the halfway socket where an extender could sit, rather than only the dead zone.
3. Check whether changing the device position or using an existing Ethernet connection solves the problem.

Compare the options

• Compact plug-in extender

  Usually suitsOne lightly used room with a clear socket at a good relay point.

  Watch forSocket placement and shared wireless capacity can limit the result.

• Dual-band extender

  Usually suitsA busier room where compatible devices need a choice of bands.

  Watch forA second band does not compensate for a weak connection back to the router.

• Mesh or wired access point instead

  Usually suitsSeveral weak rooms, roaming devices or a location with an Ethernet route.

  Watch forMore setup or cabling, but better matched to a wider coverage problem.

Keep narrowing the choice

• Mesh vs extender
• Fix Wi-Fi dead zones
