A Wi-Fi dead spot is a room or corner where the signal drops or disconnects. Before buying anything, work through these free fixes — then upgrade only if you still need to.
Free fixes to try first
- Reposition the router — central, elevated, and out in the open. Corners and closets kill range.
- Point antennas correctly — for multi-floor coverage, angle some horizontally.
- Switch bands/channels — 2.4 GHz travels further through walls; 5 GHz is faster at close range. Change to a less crowded channel.
- Remove interference — keep the router away from microwaves, cordless phones, and large metal objects.
- Update firmware and reboot.
If free fixes aren’t enough
- Wi-Fi extender — cheapest option; fine for one stubborn room, but can halve speed.
- Mesh system — the best fix for whole-home dead spots; nodes hand your devices off seamlessly.
- Wired access point / powerline — most reliable if you can run Ethernet or use existing wiring.
How much hardware do you need?
Use our Wi-Fi Coverage Estimator to see whether a single router, a 2-node, or a 3-node mesh suits your home. Then compare mesh systems and extenders on Amazon.
