About this app

WiFi Dead Zone Finder helps you understand where your Wi-Fi works well, where it becomes weak, and what may be affecting your connection.

Instead of checking the signal only next to your router, measure the places where you actually use Wi-Fi — your living room, bedroom, office, kitchen, hallway, or any custom room.

Run quick room tests, compare changes, inspect nearby networks, and analyze channel congestion from one simple app.

Find Wi-Fi weak spots around your home

Measure Wi-Fi signal strength and stability in different rooms to discover areas with weaker coverage.

Each room test collects multiple signal samples and gives you an easy-to-understand coverage result, helping you see which areas may need attention.

Quick 15-second room tests

Choose a room, keep your phone at the place where you normally use Wi-Fi, and start a short measurement.

WiFi Dead Zone Finder analyzes signal strength and stability during the test so you can compare coverage between different parts of your home.

Compare before and after

Moved your router?

Changed the position of a Wi-Fi repeater?

Added or relocated a mesh node?

Save a baseline measurement and run another test after making changes. Compare the results to see whether your adjustment actually improved coverage.

Monitor live Wi-Fi health

View useful information about your current connection, including signal strength, Wi-Fi band, connection details, and recent signal behavior.

Your home coverage summary makes it easier to identify the rooms that may have weaker or less stable Wi-Fi.

Scan nearby Wi-Fi networks

Inspect visible wireless networks around you and compare useful information such as:

• Signal strength in dBm
• 2.4 GHz, 5 GHz, and supported 6 GHz networks
• Wi-Fi channel
• Channel width
• Security type
• Connected network status
• Nearby access point signal levels

Search and filter networks to quickly focus on the information you need.

Compare Wi-Fi signal strength

See recent scan samples in a visual comparison chart.

This makes it easier to understand which nearby networks have stronger or weaker signals and how their signal levels change over time.

Analyze channel congestion

Wi-Fi performance can be affected when many nearby networks use the same or overlapping channels.

WiFi Dead Zone Finder visualizes channel overlap and helps you identify less crowded channel candidates based on nearby access points, their signal strength, channel, and channel width.

Switch between 2.4 GHz, 5 GHz, and supported 6 GHz information to better understand your wireless environment.

Useful for

Finding weak Wi-Fi areas at home, checking coverage after moving a router, testing Wi-Fi repeaters or mesh systems, comparing rooms, inspecting nearby wireless networks, and understanding channel congestion.

WiFi Dead Zone Finder is designed to turn technical Wi-Fi information into simple, practical insights so you can make better decisions about your home network.

Please note: Wi-Fi signal strength, channel availability, and network information depend on your Android device, Android version, router, and local wireless environment. Wi-Fi link information does not represent your actual internet download or upload speed.
