Wi‑Fi analyzer apps

You don’t need fancy tools to diagnose dead zones, but a good analyzer app helps you see signal strength (RSSI), channels, and which band you’re actually on.

What to look for

Recommended approach (platform-agnostic)

  1. Do a walk test while watching RSSI.
  2. If RSSI is fine but performance is bad, suspect interference or backhaul.
  3. If RSSI is bad, fix placement/backhaul before chasing channels.

Optional hardware (if you want to buy a tool)

Most people don’t need this, but you can search for handheld Wi‑Fi analyzers on Amazon:
