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
• Fully customizable status icon display options
• Dark mode support
• Accurate dBm to percentage (%) conversion
• Real-time graphs for signal strength and noise level, Signal-to-Noise Ratio (SNR), transmit rate, or MCS index (if supported)
• Signal quality ratings based on SNR measurements
• Automatic channel recommendations*
• Notifications and event logging for common events, such as when the computer joins to or disconnects from a network, roams to a different access point, or when data rate or channel configuration changes are detected
• Comprehensive app's help describes how to use the tool the most effective way

Requires a Mac with built-in Wi-Fi. External Wi-Fi adapters are not supported.

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

* 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).


Release Notes:

• Minor bug fixes.
• Updates vendors database.

If you find WiFi Signal useful and have a couple of minutes, please share your thoughts by leaving a review in the Mac App Store. It will make a huge difference to me!

Does Just What It Promises - I bought this app to help analyze the precise location of wifi dead spots in houses where I live or visit. It’s done the trick, and shown me how much better the 2.4GHz option is for going through walls than the tempting newer 5GHz. Without the clear percentages offered by the app, I’d still be using 5GHz because it is freer of interference from other devices and gadgets. Brick walls and HVAC stacks are the main culprits, and WiFi Signal is an inexpensive way to figure out the best frequency and channel to cope with the problems. There is a granularity of display options for the menu bar that is very helpful and unique. In short, I believe you can purchase this app for your Mac with confidence that you’re getting your money’s worth — and more.

Review by GulfBob

Clear display and easy to use - I use this every day to see if it is my location, lots of users on a channel, or a Comcast delay. Super easy to use. Menu bar app- click once to open; then click again to close. Accurate info about strength of the Wifi signal you are getting in real time, so you can move your desktop and laptop around to get the best signal. Also recommends better channels if you have a lot of neighbors using your channel. Been using it reliably for years. One of my best app purchases.
