Old Android phones can rebroadcast Wi-Fi as a hotspot to extend home network coverage at no cost
↗
An old Android phone's built-in hotspot feature can rebroadcast your existing Wi-Fi signal into dead zones without buying new hardware.
This is a zero-cost alternative to a commercial Wi-Fi extender or mesh node for patchy coverage areas. The tradeoff is that it creates a separate network with no seamless roaming, no smart home integration, and any commercial solution will outperform it.

Android's built-in hotspot setting lets a phone connect to Wi-Fi and rebroadcast it as a separate network, requiring no extra apps or hardware.
The phone should be placed halfway between the router and the dead zone and kept plugged in, as continuous hotspot use drains old batteries fast.
This approach won't boost internet speed, lacks smart home integration and seamless roaming, and will be outperformed by any commercial extender or mesh node.
