Tools to Fix Wi-Fi Dead Zones

The problem, in plain words: “My home Wi-Fi has poor coverage in the back bedrooms, causing dropped Zoom calls and preventing my kids from gaming upstairs.”

NetLens fits best, with 1 more that fits too.

You need reliable whole-home Wi‑Fi coverage so video calls and gaming work from the back bedrooms.

What fits

NetLensstrong · 88

NetLens is a dedicated Wi‑Fi surveying tool that creates live signal heatmaps as you walk a home, helping you locate dead zones and decide where to place access points or nodes to restore stable Zoom calls and low-latency gaming.

Best for: Homeowners who want to map actual signal strength room-by-room to plan node placement or fixes.

Caveat: Android-only app, so it requires an Android device to run the survey.

WiFi Heatmapstrong · 80

WiFi Heatmap is a browser-based predictive planner that lets you upload a floorplan, place APs, and see predicted dBm coverage so you can design where to add mesh nodes or extenders to support video calls and gaming in back bedrooms.

Best for: People who want a quick, privacy-friendly way to plan AP/node placement before buying hardware or drilling holes.

Caveat: Built for home labs and small offices — it is not intended for large enterprise multi-floor deployments.

Partly fits

Mac-native diagnostics that pinpoint channel congestion and roaming issues but is limited to Mac users.

Won’t cover: Focused on diagnosing Wi‑Fi issues from a Mac rather than surveying whole-house coverage for placement planning.

TP-Link Deco for Home Assistantpartial · 62

Provides deeper diagnostics for TP‑Link Deco mesh owners, useful for optimizing an existing Deco mesh but only applies if you already use Deco and Home Assistant.

WhyFipartial · 62

macOS tool that narrows whether problems come from Wi‑Fi, the router, ISP, or DNS, which helps triage dropped calls, but it is Mac-focused rather than a coverage planner.

Won’t cover: Designed to diagnose the root cause of connectivity problems on a Mac rather than provide a whole-home coverage survey or planning tool.

WiFi Analyzerpartial · 56

Android channel-congestion analyzer that helps pick less-crowded channels and find bandwidth-hogging devices, useful for improving performance in overlapping-network environments.

Won’t cover: Helps resolve channel congestion and interference but doesn't produce a whole-home coverage heatmap to plan node placement.
