WiFi Signal

By Adrian Granados

Open the Mac App Store to buy and download apps.


Monitor and troubleshoot the quality of your Wi-Fi connection.

WiFi Signal is a system menu bar application that provides easy access to your Wi-Fi connection details (name, channel, transmit rate, signal strength, noise, etc.), monitors the signal quality of your wireless network, and can find and recommend alternative channels for your network thus avoiding signal overlapping and channel conflicts that can result in connectivity issues and performance degradation.


• Simple, straightforward user interface
• Accurate dBm to percentage (%) conversion
• Real-time signal strength and noise level graph
• Signal quality ratings based on Signal-to-Noise Ratio (SNR) measurements
• Automatic channel recommendations*
• Comprehensive app's help describes how to use the tool the most effective way

For a more comprehensive analysis of the Wi-Fi environment consider WiFi Explorer, also available in the Mac App Store.


If you have something good to say about WiFi Signal, please share it with others by writing a review on the Mac App Store. If you find a problem or have a concern, please visit the WiFi Signal Support website and send me a message so we can resolve it.

* Due to limitations of the Wi-Fi scanning framework, channel recommendations are based solely on the detection of other Wi-Fi signals, and do not consider external sources of interference or hidden networks (i.e. networks that do not broadcast their SSIDs).

Extremely useful

If you use WiFi in a building with lots of competing WiFi networks, this is aqn invaluable app to analyze the WiFi landscape. It tells you if your WiFi channel is strongest for your location, and if not recommends a stronger channel.

A great little menubar app

Has some really useful information, and I think it's worth $0.99

I've been dropping my connection at work and it's nice to keep an eye on signal strength an noise.


Used to be good but now crashes in Maverick upon starting up. This needs to be fixed right away!!!
