WiFi Signal: Strength Analyzer 4.5 for Mac Free Download

WiFi Signal is a utility that monitors the quality of your Wi-Fi connection in real time: it displays signal, noise, transmission speed, channel, and helps diagnose problems with your wireless network.

The app runs in the background and displays key metrics of your current network right in the menu bar. Click the icon to see detailed information, graphs, and notifications about connection changes

Features:

Detailed connection information:
• Network name (SSID), BSSID (MAC address of the access point), hardware vendor
• Signal in dBm and percent, noise level, SNR (Signal-to-Noise Ratio)
• Frequency (2.4 / 5 / 6 GHz), channel number, channel width (20/40/80/160 MHz)
• Transmission rate (Tx Rate), MCS index, number of spatial streams (NSS)

Customizable display in the menu bar:
• Fully customizable template: choose which metrics to show and in what order
• Two-line support for displaying more data
• Annotations: assign clear names to access points (“Kitchen”, “Office”) for quick identification

Real-time graphs and monitoring:
• Dockable window with graphs of signal, noise, SNR, and speed
• Visual assessment of connection quality based on measurements

Smart notifications and logging:
• Alerts for access point changes, channel changes, and speed drops
• Event log for analyzing connection problems
• Threshold notifications (e.g., “signal dropped below -75 dBm”)

Channel recommendations:
• Air traffic congestion analysis and free channel suggestions
• Note: recommendations are based only on visible networks, without taking into account hidden sources of interference

Integrations and compatibility:
• Annotations sync with WiFi Explorer / WiFi Explorer Pro (from the same developer)
• Support for WPA3, Wi-Fi 6 (802.11ax), and Wi-Fi 6E (6 GHz on compatible Macs)
• Light / dark theme, adapts to system settings.
