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.
FEATURES
• 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).

Much more helpful than the stock macOS menu bar WiFi icon
Nellswor
Being able to see exactly which AP I am connected to is invaluable. To get good 5GHz coverage, I have 5 access points distributed throughout my house, connected to my router via Ethernet, with a common SSID. Adrian’s WiFi Explorer app lets me assign a label (aka Annotation) to each AP based on the AP’s BSSID, or MAC address. These labels are remembered and synced to WiFi Signal. So rather than giving me an obscure MAC address, WiFi Signal will tell me I am connected to e.g. “AP3 Back Room”.
It will also give you popup alerts when you roam from AP to AP, which gives you a good idea of your AP coverage.
Great app and fantastic support to boot! Thanks Adrian.

Clear display and easy to use
GulfBob
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.

I still love this app
willbklyn
Buying this app finally pushed me to move my wifi set up, because it was obvious where the gaps in my signal were. now my patio has strong service so my music never drops out. if you like tweaking your systems you will love having this little app. two words - Bra-Vo
