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
- RSSI readout (dBm) while you walk your house
- Band info (2.4/5/6 GHz) so you don’t confuse range with speed
- Channel congestion (especially in apartments/townhomes)
Recommended approach (platform-agnostic)
- Do a walk test while watching RSSI.
- If RSSI is fine but performance is bad, suspect interference or backhaul.
- 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:
